Chemical constituents from Solanum lyratum Thunb / 军事医学科学院院刊

ABSTRACT

Objective To investigate the chemical constituents of the 60% alcohol extract of Solanum lyratum Thunb..Method The compounds were isolated by column chromatography over silica gel and Sephadex LH-20 and preparative TLC.Their structures were elucidated on the basis of physicochemical property and spectral data.Resulut Eleven compounds were isolated and identified as:ononin(1), genistin(2), 5-hydroxyl ononin(3), formononetin(4), daidzein(5), daidzin(6), 4-hydroxy-benzaldehyde(7),vanillic acid(8), protocatechuic acid(9),ethyl-α-D-arabinofuranoside(10) and ursolic acid(11).Conclusion Compounds 1,2,3,10 and 11 are isolated from S.lyratum for the first time.
