Studies on the Chemical Constituents from Spatholobus sinensis(II)

Objective:To investigate the chemical constituents from Spatholobus sinensis.Method: The chemical constituents were isolated by solvent and chromatography methods.The structures were identified on the basis of chemical methods and spectroscopic evidence.Result: Eight compounds were identified as zizyvoside Ⅰ(1),spatholosineside B(2),ethyl 2,4-dihydroxybenzote(3),bis(2-ethylhexyl) benzene-1,2-dicarboxylate(4),2-palmitoylglycerol(5),1-(26-hydroxyhexacosanoyl)-glycerol(6),lupeol(7) and β-sitosterol(8).Conclusion: Among these compounds,compound 2 was new,and compounds 7,8 were isolated from S.sinensis for the first time;compounds 1,3-6 were isolated from the genus Spatholobus for the first time.
