RESUMEN
OBJECTIVE: To study the chemical constituents of Sapium sebiferum leaves. METHODS: The chemical constituents in the petroleum ether and n-butyl alcohol parts of the 95% ethanol extract of Sapium sebiferum leaves were isolated and purified by chromatographic methods. Their structures were elucidated by spectral data and physicochemical properties. RESULTS: Twelve compounds were purified and identified as squalene(1), 3β-hydroxyglutin-5-ene(2), fraxetin(3), friedelin(4), β-sitosterol(5), gallic acid ethyl ester (6), quercetin (7), 5-hydroxymethylfurfural (8), blumenol C glucoside (9), kaempferol-3-O-β-D-glucopyranoside (10), 1'-O-benzyl-α-L-rhamnopyranosyl-(1″-6') -β-D-glucopyranoside(11), and shikimic acid(12). CONCLUSION: Compounds 1-3, and 8-12 are isolated for the first time from this plant.
RESUMEN
Plants have provided a source of inspiration for novel drugs compounds, as plant derived medicines have made large contributions to human health and well-being. In present study, the methanolic, ethanolic, chloroformic and petroleum ether extracts of Sapium sebiferum leaves were investigated for their antifungal activity against Aspergillus niger and Aflatoxigenic Aspergillus flavus. Results obtained showed that all the extracts reduced colony growth by 1-32%. It was found that among all the leaf extracts, methanolic and ethanolic extracts have maximum percentage growth inhibition (26%) against Aspergillus flavus, while methanolic extracts showed maximum percentage growth inhibition (32%) against Aspergillus niger.
RESUMEN
The Sapium sebiferum leaf extracts were determined for their antimicrobial activities against Staphylococcus aureus, Micrococcus luteus ,Pseudomonas aeruginosa, Salmonella typhi, Klabsiella oxytoca, Listeria monocytogenes, E.coli, Saccharomyeces cereviceae and Candida albicans. The antimicrobial activities of these strains were compared with standard antibiotics (amoxicillin). Results obtained showed that all the extracts except aqueous (hot and cold) were effective against all the microbial strains. The methanolic extract of Sapium sebiferum leaves was most effective against all the bacterial strains and thus displayed highest zone of 21.0 mm at concentration of 100 mg/ml against Listeria monocytogenes ( MIC value is 25 mg/ml). Salmonella typhi and Klabsiella oxytoca did not show any activity. The anticandidal activity of methanolic, ethanolic and petroleum extracts showed maximum inhibition zone of 24.0 mm (MIC value is 25mg/ml).
