Abstract:

Ticks and tick-borne diseases are a major constraint for the sustainable cattle industry in the tropical and subtropical regions of the world. The developments of resistance to most of the commonly used acaricides lead to an attempt to screen herbal products and their combinations for their possible acaricidal activity to develop an eco-friendly tick control alternative. Essentria^® IC-3 insect concentrate for crawling and flying insect pests contains rosemary oil (10%), geraniol (5%) and peppermint oil (2%), and acts on target pests by octopamine blocker technology. Essentria and its active components were evaluated for acaricidal activity against acaricide resistant (Yucatan and El Zamora) and susceptible strains (Deutch) of cattle tick, Rhipicephalus (Boophilus) microplus by Larval Packet test (LPT) using 14-21 days old unfed larvae. The efficacy was assessed by measuring percent larval mortality and estimating lethal concentrations at 50% (LC₅₀) and 95% (LC₉₅) with 95% confidence limits (CL) using probit analysis. A concentration-dependent mortality response was observed with Essentria and geraniol whereas; rosemary oil and peppermint oil failed to produce such response against any tick strain. The LC₅₀ and LC₉₅ (95% CL) values of Essentria and geraniol against Deutch strain were 0.55% (0.55-0.56) and 0.10% (0.98-0.10), and 0.59% (0.58-0.60) and 0.11% (0.10-0.11), respectively. Interestingly, the acaricide resistant strains showed resistance to Essentria with resistance factor (RF) of 1.49 (Yucatan) and 2.20 (Fipronil resistant) but against geraniol, susceptibility similar to susceptible (Duetch) strain was also recorded in resistant strains. We report resistance against a herbal acaricide in cattle tick for the first time, possibly due to cross-resistance to fipronil.

Abstract:

Marquesas islands (French Polynesia), have a strong culture which is still very conspicuous today. Natural fragrance is an important characteristic of Marquesan beauty concern, flowers and fragrant plants being omnipresent in traditional cosmetic preparations. This study, the first specific inquiries on the French Polynesian “cosmetopoeia”, is based on ethnobotanical investigations focusing on traditional cosmetic. Ethnobotanical surveys of Marquesan traditional practitioners were performed in Tahiti and in Nuku Hiva islands. Prior to each interview process, a free and informed consent PIC (Prior Informant Consent) was signed by both interviewer and informant. A semi-directive methodological approach with open-ended questions was performed and allowed to establish a list of cosmetic allegations per target or per use. Survey was based on three standards: application area (hair, body, face), uses (care, protection, hygiene, embellishment and perfume), and ethnobotany. Coconut (Cocos nucifera) is the most used species as a traditional cosmetic ingredient. Ocimum basilicum (basil) and Curcuma longa (turmeric) are the second most important plants. This study allowed to document a list of more than 500 recipes with almost 80 different plant species. For example, for hair care, natural shampoo were mainly constituted of 'ekapuhi plant - shampoo ginger (Zingiber zerumbet), and for baby care, daily bath are given with cooked leaves of Annona muricata (soursop) or other plants. There is a very close link between traditional cosmetic uses (Cosmetopoeia) and pharmaceutical uses (Pharmacopoeia), but compared to pharmacopoeia, cosmetopoeia involves more native species. It symbolizes the practice of a lively heritage in the Marquesas archipelago.

Abstract:

Paeoniae Radix (Latin name for crude drugs) is defined as the root of Paeonia lactiflora Pallas (: peony in English and Shakuyaku in Japanese) in the Japanese Pharmacopoeia. It is one of the most popular herbal medicines and mainly used as sedative, antispasmodic and astringent in Kampo medicine (traditional Japanese medicine) and Traditional Chinese Medicine. Especially in Kampo medicine, herbal medicines are used as prescriptions, the mixture of several kinds of crude drugs. We focused on one of Paeoniae Radix containing Kampo prescription, Tokishakuyakusan (TS) which is frequently used for improvement of blood circulation. We prepared two kinds of TS containing two different kinds of Paeoniae Radix; one is selectively bred strain in Japan for medicinal use and another is Western cultivar. Both of those prescriptions were effective for anemia patients (n=12) as shown by the improvement of several hematological parameters, but those effects were statistically different. We focused on iron, but there were no differences in its content of both prescriptions. We also investigated the state of the iron by analyzing Mössbauer spectra and found the differences in the spectra. In this investigation, we used the traditional form of TS which are composed by the directly powdered crude drugs. We suggested the efficacy of TS for anemia and the relation between the quality of Paeoniae Radix and the clinical effects of the prescription.

Abstract:

Acne vulgaris is a chronic dermatologic disease with four factors involved in the development of lesions. Treatments need to address as many of these underlying factors as possible in order to reduce acne lesions. As such Purified Bee Venom (PBVTM) serum is an attractive therapeutic option for acne, but little data exists on the efficacy of this treatment strategy. In this prospective, non-comparative study, 30 subjects having mild to moderate acne vulgaris were enrolled and treated with PBVTM serum twice daily for a period of 6 weeks. Clinical evaluation of lesions by expert visual grading and image analysis were made at weeks 0 (baseline), 3 and 6. The average visual acne grade of all volunteers significantly improved with the PBVTM serum treatment at weeks 3 (p<0.05) and 6 (p<0.001) when compared with the baseline grade at week 0. In addition, there was a mean percent improvement of 8.6% and 52.3% in acne grade observed after 3 and 6 weeks of PBVTM serum use, with 20% and 77% of the subjects showing improvement, respectively when compared with baseline. Moreover, the subjects showed improvement in open comedones, closed comedones, papules, pustules and nodules after 3 and 6 weeks of PBVTM serum use. Six (6) weeks of treatment with PBVTM serum was found to be effective in the treatment of mild to moderate acne vulgaris, with no incidence of serious side effects or irritation

Abstract:

Cervical cancer is among the most frequently diagnosed cancers in females worldwide. Nujiangexathone A (NJXA), a novel compound from Garcinia nujiangensis, has been shown to have anti-cancer potential. In this study, the anti-tumor effects and the underlying mechanisms of NJXA action were investigated. Our results suggested that NJXA reduced the viability of HeLa and SiHa cells in a concentration- and time-dependent manner and induced G0/G1 cell cycle arrest in cells by down-regulating cyclins B1, E1, and A and cyclin-dependent kinases 2, 4 and 6, while selectively restoring p27. Two-dimensional gel electrophoresis and mass spectrometry revealed that heterogeneous nuclear ribonucleoprotein K (hnRNPK) was among the most affected proteins upon NJXA treatment. hnRNPK is closely linked to the cell cycle and is highly expressed in several tumors. Our study showed that NJXA reduced the expression of hnRNPK and induced cell cycle arrest through the c-Myc-cyclin/Cdk-Rb-E2F1 pathway. Moreover, in vivo results showed that the i.p. injection of NJXA significantly inhibited tumor growth on day 16 in a nude mouse xenograft model, and NJXA induced no apparent toxicity. Our study suggests that NJXA carries out anti-tumor functions by strongly suppressing the hnRNPK expression that is specifically associated with cell cycle arrest. In conclusion, NJXA is a potential anti-cancer drug candidate, especially for treating cancers with abnormally high hnRNPK expression

Abstract:

Propolis is a resinous substance produced by bees through the mixture of jaw secretions and the exudate collected from plant materials. This resin is used in the construction, maintenance, and asepsis of the nest . There are records that ancient civilizations, such as the Incas, Greeks, Egyptians, and Romans, used propolis for its therapeutic properties. Propolis from stingless bees Melipona orbigny (mandurí-de-Mato-Grosso) and Tetragonisca fiebrigi (Jataí or abelha-ouro) found in Brazil are used in folk medicine by their nutritional and therapeutic properties. Propolis from stingless bees are well known for its biologic properties; however, few studies have demonstrated these effects. Therefore, this study aimed to investigate the chemical composition and antimicrobial, antioxidant and cytotoxic activities of propolis from the stingless bee Melipona orbignyi and Tetragonisca fiebrigi  found in Mato Grosso do Sul, Brazil. The chemical composition of the ethanol extracts of propolis (EEPs) these species of bees indicated the presence of aromatic acids, phenolic compounds, alcohols, terpenes and sugars. The EEPs were actives against against American Type Culture Collection (ATCC) and hospital strains of bacteria and fungi. The EEPs showed antioxidant activity by scavenging free radicals and inhibiting hemolysis and lipid peroxidation in human erythrocytes incubated with an oxidizing agent. Additionally, EEPs promoted cytotoxic activity and primarily necrotic death in K562 erythroleukemia cells. Taken together, these results indicate that propolis from Melipona orbignyi and Tetragonisca fiebrigi have therapeutic potential for the treatment and/or prevention of diseases related to microorganism activity, oxidative stress and tumor cell proliferation.

Abstract:

Heat-clearing and detoxicating TCM is the most frequently used category in the treatment of cancerous tumors, but lacks sufficient validation studies. The present research (in our series of studies) aims to explore the anti-angiogenic effects of TCM; so we begin with heat-clearing and detoxicating TCM. Six typical heat-clearing and detoxicating TCM (Philippine Violet Herb, Wild Chrysanthemum, Heartleaf Houttuynia Herb,Chinese Lobelia Herb,Spreading Hedyotis Herband Uni- flower Swisscentaury Root) were decocted, concentrated, sieved and desiccated to attain the water ex- tract. This study utilized the vascular organism research model for Fli1a-EGFP zebrafish, which were raised and maintained under standard conditions. 22hpost-fertilization (hpf) embryos were distributed into 12-well plates for a treatment period of 26h. The TCM water extracts which were diluted in 0.1% dimethylsulfoxide (DMSO), were added to each well at a concentration of 200 μg/ml. The positive control was5 μg/ml PTK787 (vatalanib) and the vehicle control was 0.1% DMSO. At 48hpf larvae were tricaine anesthetized and imaged. To demonstrate if TCM shows angiogenesis defects, ten larvae were randomly chosen to conduct a quantitative assay. Quantitative real-time PCR was conducted to dissect the mechanisms involved by analyzing the contributions of signaling pathways and molecules concerning angiogenesis, with a total of ten genes examined. All 30 larvae treated with Wild Chrysanthemum, Uniflower Swisscentaury Root and PTK787 showed angiogenesis defects. Embryos treated with Wild Chrysanthemum and Uniflower Swisscentaury Root showed a lower number of complete intersegmental vessels (ISVs) and there was statistically significant differences between TCM and the vehicle control. Wild Chrysanthemum and Uniflower Swisscentaury Root have a higher inhibition rate and the statistical difference between TCM and the vehicle control was significant. Compared with vehicle controls, Wild Chrysanthemum could significantly modulate the relative mRNA expression of all ten genes. Whereas, Uniflower Swisscentaury Root could significantly regulate the relative mRNA expression of seven genes, it did not show a significant impact on the remaining three genes. The present research demonstrates that Wild Chrysanthemum and Uniflower Swisscentaury  Root have anti-angiogenic effects in zebrafish and that they could regulate both proangiogenic mechanisms and negative angiogenesis regulators. Their anti-angiogenic effects result from effects on negative regulators overriding their effects on proangiogenic mechanisms. The results provide new insights into their clinical application and therapeutic potential for the management of angiogenesis-dependent diseases such as cancer.

Abstract:

The historical importance of natural products as new and better pharmaceuticals, or models for them, is evident when we mention products such as taxol, vincristine, or artemisinin. Plants, and particularly medicinal plants, still represent the most important source of bioactive natural products today. Mexico is considered one of the richest countries in terms of biodiversity and in terms of cultural diversity; more than fifty ethnic groups recognize and use more than 3000 plants in their practice of traditional medicine. However, it is believed that less than 5% of these species have been studied in terms of their production of biologically active secondary metabolites. The general objective of the research carried out in our laboratory is to promote the conservation of the biodiversity of the Yucatan Peninsula, by investigating native plants used in Mayan traditional medicine as potential sources of novel and more efficient pharmaceuticals. It has been suggested that discovering natural products with biological activity in little known and less studied plant species, with potential application in economically important areas such as pharmacy and agriculture, could contribute to the protection of biodiversity. This presentation will mention the ethnomedical groups of medicinal plants (antiprotozoal, analgesic, anti-inflammatory, antidiabetic and against obesity) currently under study in our research group and present some of the chemical structures of a number of recently identified bioactive metabolites

Berit Smestad Paulsen completed her PhD from University of London, UK, and returned to School of Pharmacy, University of Oslo, Norway, being the base for the rest of her career. She for the major part of her research focused on carbohydrates, especially the high molecular ones, and their biological importance. She has studied the importance of these compounds in medicinal plants from Mali, and also performed various ethnopharmacological studies in Mali. She has published more than 200 papers in reputed journals and has been servig as an editorial board member of various journals. 

Abstract:

Medicinal plants are the major source of drugs in most of the developing countries, and in Mali more than 80% of the population relies on these for the treatment of diseases. Over the years, it has been conducted surveys in several regions of Mali where the focus for some of the interviews were based on what plants where used against wounds of different types, both external and internal. In all cases the healers were using water extracts in their treatments, and due to this it was of interest for us to study the compound being water-soluble, and especially the high molecular weight polysaccharides as they constituted the major part of the water extracts. During our interviews we also found that water extracts were used against diseases like gastric ulcer, malaria and several other ailments where we observed that the immune system might be involved.

Thus, we have studied several plants for their content of polysaccharides with focus on their structures, their effects in immunologically related bioassays and also their structure activity relations. Most of the polysaccharides are of the pectin type with a backbone of the rhamnogalacturonan type I structure with arabinogalactan type I and II structures attached. Enzymatic degradation of the pectins gave rise to fragments that were the object for the determination of the most active parts of the structures.

The presentation will include the description of the plants studied, their traditional uses as well as  discussion on the structures and their importance for the biological effects observed

Abstract:

Introduction- Head injury is a major cause of disability and death. Possible role of neuroinflammation, nitric oxide, microglia and oxidative stress have been suggested in the pathophysiology of traumatic brain injury related complications such as cognitive dysfunction.

Objective- Therefore, the present study was designed to explore the possible role of ginseng and rutin and its interaction with nitric oxide modulator and microglial inhibitor against experimental of head injury induced behavioral, biochemical and molecular alterations.

Materials and Methods- Wistar rats were exposed to head injury by using weight-drop method. Following injury and a post-injury rehabilitation period of two weeks, animals were administered vehicle/drugs for another two weeks.

Results- Traumatic brain injury caused significant memory impairment in Morris water maze task as evident from increase in escape latency and total distance travelled to reach the hidden platform. Time spent in target quadrant and frequency of appearance in target quadrant was also significantly decreased in head trauma rats. Further, there was a significant increase in oxidative stress (elevated malondialdehyde, nitrite concentration and decreased reduced glutathione, superoxide dismutase and catalase levels), neuroinflammation (TNF-α and IL-6) and acetylcholinesterase levels in both cortex and hippocampal regions of traumatized rat brain. Ginseng (100-200 mg/kg), Rutin (20-80) treatment for two weeks significantly attenuated all these behavioral, biochemical and molecular alterations, suggesting their neuroprotective effect. Further, combination of sub effective doses of ginseng (50 and 100 mg/kg) or rutin (40, 80) with microglia inhibitor as well as nitric oxide modulators significantly modulates their protective effect respectively. The present study suggests that these flavanoids produce their neuroprotective effect by involving microglial as well as nitric oxide pathways. Conclusion- The study further provides a hope that these flavanoids could be used effectively for the management of brain traumatic injury and related complication

Abstract:

The interdisciplinary scientific rationalization of traditional drugs is of great significance to present civilizations as it has a big role in supporting basic health care needs. Mainly related to treatments associated with aging, prolonged communicable diseases, traditional drugs offer promising alternatives to modern medicines. The latest trend in ethnopharmacology have led to the undiscerning use of chemical products which has given rise to several problems comprising environmental pollution, harmful residues, chemical drugs and resistance against microbes. This has strived exploration into alternate methods. The outcome from the current analysis will definitely give momentum to the area of medicinal plant research to develop viable, efficient and nontoxic substitutes against usual antimicrobial compounds. In this paper, the nanoparticles were synthesized from Moringa oleifera and their antimicrobial activity was assessed. Antimicrobial potential of leaves has been assessed for both the extracts, with and without AgNP, on different strains viz. Staphylococcus aureus, Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa and Enterococcus faecalis. Extent of inhibitory effect of both the extracts was assessed by minimum inhibitory concentration method over a concentration range of 0.075-2.4 mg/ml and standard zone of inhibition (ZOI) assay. The nanoparticles showed ZOI against almost all the studied bacteria. The water extract was found to have an antibacterial activity against gram positive and gram-negative strains. The bactericidal effect of nanoparticles is due to their size which helps them to interact with microorganisms and therefore these green nanoparticles help in increasing the antibacterial potential of plants.

Abstract:

Multi-targeted therapy is the new approach in IBD therapeutics due to its multifactorial etiology and failure to attain remission with currently available options. In the current study, we assess the pharmacological basis of both the extract and oil of Flaxseed use in IBD and compare their activity profile.

HPLC of the extract revealed the presence of polar compounds with peaks resembling quercetin, nicotinic acid and nicotinamide, whereas Flaxseed oil only showed peaks corresponding to non-polar components. Flaxseed oil was more effective in reducing the mortality rate in acetic acid (AA)-induced colitis in BALB/c mice at 500 mg/kg dose as compared to Flaxseed extract (Fs.Cr). Flaxseed oil was more effective in reduing the ulcers, whereas, Fs.Cr was more effective in reducing the inflammatory infiltration and reducing goblet cell depletion and increasing the mucin release. Antispasmodic mechanisms of Fs.Cr were mediated by phosphodiesterase enzyme inhibitory activity (PDEI) as main mechanism, followed by Ca⁺⁺ antagonist effect, as Fs.Cr dose-dependently inhibited spontaneous, carbachol (CCh) at 3 mg/ml and high K⁺-induced contractions at 5 mg/ml, in isolated rabbit jejunum with higher potency against CCh, similar to that of papaverine, while verapamil was more potent against high K⁺. This was also supported by potentiation of isoprenaline concentration-response curves (CRCs) by pretreatment with low doses of Fs.Cr (0.01 and 0.03 mg/ml). Fs.Cr mediated PDEI activity by inhibiting PDE-4 subtype as pre-treatment of Fs.Cr did not potentiate Rolipram (PDE-4  inhibitor) inhibitory activity against CCh-induced contractions, whereas it potentiated the inhibitory effect of Cilostazol (PDE-3 inhibitor) and zaprinast (PDE-5 inhibitor). Subsequent dose dependent increase in cAMP levels (1 and 3 mg/ml) was also evident similar to papaverine (1 mM and 3 mM doses), further supporting its PDEI effect. Flaxseed oil’s main antispasmodic activity was by K⁺ channel opening (KCO) mechanism (3 mg/ml), followed by a weak PDEI activity as it inhibited CCh-induced contraction at 5 mg/ml. Flaxseed oil was more potent and efficacious bactericidal against enteropathogenic Eschericia.coli (EPEC), enterotoxigenic E.coli (ETEC) and enteroaggregative E.coli (EAEC) which are implicated in IBD, as they killed these microbes at 9 µg/ml and 14 µg/ml, whereas, Fs.Cr was only cidal against EPEC at a 10 times higher dose than of Flaxseed oil (100 µg/ml), whereas, it had a static mechanism against ETEC and EAEC.

Our results indicate that both Flaxseed oil and Fs.Cr have constituents that are effective against IBD model of mice with different activity profile. Hence, Flaxseed as a whole may produce an augmented response.

Abstract:

Fatty foods, the most common diet today are the crux of many metabolic disorders which need urgent attention. Garcinia pedunculata Roxb. (GP, Clusiaceae) is a plant found available in northeast (NE) region of India, is considered to have versatile therapeutic properties. The people of this region have been using dried pulp of GP fruit for the treatment of different stomach related diseases traditionally. This study aimed at evaluating the potential therapeutic action of the polyphenol-rich methanolic extract of the fruit in experimental induced obese rats. In vitro antioxidant and antidiabetic activity of GP extracts, i.e. fruit extract (GF) and seed extract (GS) were determined by using various methods viz., 1,1-diphenyl-2picrylhydrazyl (DPPH), 2,2-Azinobis (3-ethylbenzthiazoline-6-sulphonicacid) (ABTS^.+), nitro blue tetrazolium (NBT) and α-glucosidase inhibition assay for detection of antihyperglycemic activity. In vivo antilipidemic and antiobesity activities were evaluated by administrating oral dose of GF for 60 days on a high-fat diet (HFD) induced hyperlipidemia in rat. GF showed higher antioxidant activity than GS by DPPH radical scavenging (IC50D 4.01 mg/ml), ABTS^.+ (IC₅₀=0.82 µg/ml), NBT (IC₅₀=0.07 µg/ml) and also showed notable α-glucosidase inhibitory activity (IC50=19.26 µg/ml). Furthermore, GF treated rat revealed a reduction in the body weight (~60%), serum total cholesterol (33%), triglycerides (32%), low-density lipoprotein (38%) and liver biomarker enzymes after 60 days HFD fed animals. Simultaneously, GF supplementation significantly protected the HFD induced changes in hematological parameters. Histological observations clearly differentiate the structural changes in liver of HFD and GF treated group. This novel dietary lipid adsorbing agent of GF exhibited prevention of hyperlipidemia induced by HFD in the rat

He is now pursuing a Post-graduation Residency in Gynecology and Obstetrics and is also Chairman of the Anti-drug Addict Movement at University of Gondar. He has conducted more than 3 papers in the area maternal use of herbal remedies which are now submitted for publication to international reputed journals.

Abstract:

Statement of the Problem: Improving maternal and child health is one of the public health priorities in several African countries including Ethiopia. However, research on herbal medicine use during pregnancy is scarce in Ethiopia. The present study aimed at assessing the prevalence and correlates of herbal medicine use among pregnant women on antenatal care (ANC) follow-up at Gondar University Referral Hospital, Ethiopia. 

Methodology & Theoretical Orientation: An institutional-based cross sectional study was conducted on 364 pregnant women attending ANC clinic from March to May 2016 at University of Gondar Referral and Teaching Hospital, northwest Ethiopia. Data on socio-demography, pregnancy related information as well as herbal medicine use was collected through an interviewer-administered questionnaire. Descriptive statistics, univariate and multivariate logistic regression analysis were performed to determine prevalence and associated factors of herbal medicine use. 

Findings: From 364 respondents, 48.6% used herbal medicine during current pregnancy. Ginger (40.7%) and garlic (19%) were the two most commonly used herbs in pregnancy. Common cold (66%) and inflammation (31.6%) were the most common reasons for herbal use. Majority of herbal medicine users (89.8%) had not consulted their doctors about their herbal medicine use. Rural residency (Adjusted odds ratio (AOR): 3.15, confidence interval 

(CI): 1.17-6.14), illiteracy (AOR: 4.05, CI: 2.47–6.62) and average monthly income less than 100 USD (AOR: 3.08CI: 1.221-7.77) were found to be strong predictors of herbal medicine use.

Conclusion & Significance: The use of herbal medicine during pregnancy is a common practice and associated with residency, level of education and average monthly income. From the stand point of high prevalence and low disclosure rate, the health care providers should often consult pregnant women regarding herbal medicine use.

He has won several research grants and has published extensively in peer reviewed journals. One of his current research activities is on the ergot fungus, ergot alkaloids and ergotism on the Ethiopian highlands.

Abstract:

Ergotism is a current health problem on many areas of the highlands. A few epidemics of ergotism in Ethiopia have been documented in the last few decades, the first one in 1979. The problem continues to date and a multi-purpose research was undertaken. Field studies showed that the problem is prevalent on highlands between 2,500-3,000 m above sea level and where barley and wild oats (Avena abyssinica) are grown as major crops. It was found that A. abyssinica is the only cereal host for the Ethiopian ergot fungus. Based on preliminary mycological studies, the fungus is a variety of Claviceps purpurea. Both gangrenous and convulsive ergotism is apparent in affected communities with symptoms typical of ergotism. The invasion of the ergot fungus and development of the sclerotium in farmers’ fields is unpredictable possibly due to climatic changes. Farmers, unfortunately, are not aware of the source and cause of the problem and the disposing factors for high prevalence and abundance of the sclerotium in their fields in certain years is unclear. It is apparent that a cocktail of toxic ergot alkaloids caused by ingestion of the sclerotium from infected oats is the cause of the problem. It will be interesting to know the quality and quantity of alkaloids present in the sclerotium. There are good reasons to anticipate new ergot alkaloids from the Ethiopian ergot fungus. To solve the problem of ergotism in Ethiopia, an ecological perspective and approach on research and intervention is required

Abstract:

Holarrhena pubescens belongs to the family Apocynacea, commonly known as “Kurchi” is highly reputed in traditional medicine as a remedy for amoebic dysentery and other intestinal ailment. Bioassay-directed fractionation of the ethanolic extract of Holarrhena pubescens resulted in the isolation of steroidal alkaloids i.e. holamide and pubscinine. Holamide showed a three proton doublet at 1.45 (J=6.56 Hz) and two AB doubles at 3.17 and 3.00 each for on proton (J=12.06 Hz) in the 1H NMR spectrum suggested that it belongs to conanine series of alkaloid (A class of compound with the steroid nucleus and a five members heterocyclic ring with nitrogen). In contrast, pubscinine showed one methyl at 1.28 while the doublet is missing a three proton singlet was observed at 2.28 due to a vinylic methyl indicated a double bond in the 18,20–epimino ring of the conanine series of alkaloids. In anaesthetized rats, the holamide and pubscinine caused a fall in blood pressure in a dose-dependent manner. Pretreatment of animals with atropine completely abolished the hypotensive response of acetylcholine; whereas hypotensive effect of holamide and pubscinine were not modified by atropine. Similarly, acetylcholine produced contractile effect in guinea-pig ileum, which was antagonized by atropine, however both (holamide and pubscinine) failed to produce any stimulant response on guinea-pig ileum. These data indicate that the steroidal alkaloids i.e. holamide and pubscinine from Holarrhena pubescens mediated hypotensive response through a mechanism different to that of acetylcholine

Abstract:

The use of botanical raw materials to produce pharmaceuticals, herbal remedies, dietary supplements and many  industrial materials constitute an important global resource in terms of healthcare and economy. In Nigeria and other developing countries, the indigenous knowledge on the uses of plants lies maily with the olders who are decreasing in number due to death and other unforeseen occurrences. An Ethno-botanical survey was carried out to obtain information on the ethno medicinall  plants used by the people of Gombe State, North-Eastern Nigeria, in  curing enteric fever. Oral interviews were conducted and 34 informants availed themselves for the interview and were consulted. All relevant information obtained from the respondents was recorded. Valid nomenclature, along with local names, family names, part of the plant(s) used, methods of preparation and administration and 54 plant species belonging to 27 families as well as 7 unidentified species that are commonly used by the people of the state in ethnomedical treatment of the ailment were documented. Those interviewed included traditional practitioners, local herb sellers, traditional rulers, hunters, farmers and patients.  Results showed that the people of Gombe State are knowledgeable on herbal medicine in the treatment of diseases and ailments. However,  further scientific validation of the traditional claims of anti-typhoid properties is imperative. This would establish their candidature for any possible future research for active principles and the possible development of new cheaper and more effective anti-typhoid drugs, as well as in the conservation of this rich diversity of medicinal plants.

Abstract:

Oxidative stress induced neuronal cell deaths are one of the major cause of neurodegenerative diseases. Often such stress can instigate, reactive oxygen species (ROS) mediated neuronal cell apoptosis and necrosis. Previous studies have been focused towards identification of potential neuroprotective agents that can prevent oxidative stress-induced neuronal cell damage. However, availability of various chemotherapeutic agents for alleviating devastating disorder which provide symptomatic relief and may turn ineffective or show adverse drug effect after prolonged use. Alternative source for controlling the progression of such diseases could be plant derived metabolites (phytochemicals) that regulate neuronal malfunction, with slow sustained effect and no side-effects would appear to have significant neuroprotective effects. Several medicinal plants, designated as “Rasayan Drugs” in Ayurveda are reported to have significant influence on brain functions. Bacopa monnieri, a well-documented nootropic plant, is extensively used in herbal formulations for neurological disorder. Bacopa monnieri plant has learning and memory antidepressant activity, anticonvulsive action and antioxidant activity. Therapeutic activities of plant are attributed due to the presence of active phytocompounds viz. saponins, flavonoids and alkaloids. However, variations in active phyto-pharmaceutically important compounds in such formulations often affect their therapeutic efficacy and market acceptance. Current study highlights the comparative cytoprotective potential of field acclimatized and in vitro propagated Bacopa monnieri extracts of different locations on neuronal cell line (HT-22/N2a).
