引用

Chinese Journal of Natural Medicines 2014年第4期12卷 273-283页

作者： Mercy B.Obogwu Abidemi J.Akindele Olufunmilayo O.Adeyemi Department of Pharmacology Faculty of Basic Medical Sciences College of Medicine University of Lagos

AIM: Hepatotoxicity is a significantly increasing health problem worldwide, and the extent of the problem has stimulated interest in the search for hepatotherapeutic agents from plants. This study investigated the hepatoprotective and in vivo antioxidant activities of the hydroethanolic extract of Mucuna pruriens leaves in antitubercular and alcohol-induced hepatotoxicity assays in rats. METHOD: In each of the models used, seven groups were allotted. The different groups received normal saline(10 mL·kg-1, p.o.); hepatotoxicant(isoniazid-rifampicin, INH-RIF, 100 mg·kg-1, i.p. or 20% ethanol 5 g·kg-1, p.o.) and normal saline(10 mL·kg-1, p.o.); hepatotoxicant and extract at doses of 100, 200, and 400 mg·kg-1 p.o.; hepatotoxicant and silymarin 50 mg·kg-1 p.o.; and extract at 400 mg·kg-1 p.o.. On the 21st day of treatment, blood was collected for assessment of serum biochemical parameters and harvested liver samples were assessed for antioxidants. RESULTS: The hepatotoxicants significantly(P < 0.05-0.001) increased the levels of alanine transaminase(ALT), aspartate transaminase(AST), alkaline phosphatase(ALP), bilirubin, and malondialdehyde(MDA); and reduced the levels of catalase(CAT), superoxide dismutase(SOD), glutathione peroxidase(GPx), and reduced glutathione GSH compared to control. M. pruriens significantly reversed(P < 0.05-0.001) the elevation in the level of ALT, AST, ALP, and bilirubin caused by the hepatotoxicants. The extract(200 and 400 mg·kg-1) significantly reversed(P < 0.05) the diminution in the level of in vivo antioxidants and increased the level of MDA produced by INH-RIF. M. pruriens(100-400 mg·kg-1) elicited significant reduction(P < 0.001) in the level of MDA compared to the alcohol group. Silymarin also reversed the deleterious effects of the hepatotoxicants. CONCLUSION: The hydroethanolic extract of Mucuna pruriens leaves possesses hepatoprotective activity with enhancement of in vivo antioxidants as a possible mechanism of action.

Chemical Compositions of Lonchocarpus cyanescensBenth., (fabaceae)—Case Study of Its Volatile Oils, and Two Triterpenoids

引用

American Journal of Plant Sciences 2013年第8期4卷 1653-1659页

作者： Dorcas Olufunke Moronkola Ibrahim Adebayo Oladosu Department of Chemistry University of Ibadan Ibadan Nigeria.

Leaf and stem essential oils of Lonchocarpus cyanescens Benth., (fabaceae) were obtained by hydro-distillation, using all-glass apparatus adapted to British Pharmacopeia specifications with yields of 0.03% and 0.17% respectively. The oils were investigated by GC and GC-MS analyses. Results show seven compounds were responsible for 90.4% of leaf;eleven compounds responsible for 97.6% of stem volatile oils. Phytol (62.5%) and hexadecanoic acid (12.4%) dominate the leaf oil;octadecenoic (24.1%) and hexadecanoic acids (17.2%) are predominant in the stem oil. Phytochemical screening of stem, leaf, and root methanol extracts of Lonchocarpus cyanescens reveal presence of following seven classes of metabolites: saponin, tannin, steroid, terpenoid, cardiac glycosides, phlobatannins and flavonoids. Partitioning of methanol extract from dried leaf of it with ethylacetate gave fraction, which was chromatographed using gradient elution. TLC with high Rf was used in monitoring elution. Two white crystalline solids eluted at 5% and 10% ethylethanoate in hexane, were re-crystallized and characterized. They were subjected to Infra-Red spectra, mass spectrometry (ESI technique), 1H and 13C-NMR analyses, which confirmed they are triterpenoids. Above mentioned metabolites may be responsible for literature acclaimed bio-activities L. cyanescens display [anti-inflammatory, anti-arthritic, anti-microbial effects]. This paper presents details of above results which are new in literature.
