Abstract:
AIM: To study the chemical constituents from leaves of Ampelopsis sinica. METHODS: The chem-ical constituents were isolated by column chromatographic methods, and the structures were elucidated on the basisof IR,~1H-NMR, ~(13)C-NMR, MS spectral analysis. RESULTS: Nine compounds were isolated and their structures were identified as quercetin β-sitosterol,vanillic acid,3,5-dimethoxy1-4-orthohydroxybenzoic acid ,epicatechin,api-genin, kaempferol, 5,7,3',4'-Tetrahydroxyflavone-3-O-6-rhamnose, rutin. CONCLUSION: All compounds are isolated from leaves of this plant for the first time.
