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.
ABSTRACT
Objective To investigate the chemical constituents of Rannunculus chinensis Bunge..Methods The chemical constituents of R.chinensis were isolated by chromatography on silica gel and Sephadex LH-20. The structures of compounds were identified by phytochemical properties and spectral analysis(MS and NMR).Results Ten compounds were isolated and identified as quercetin(1),kaempferol(2),luteolin(3),quercitrin(4), protocatechuic acid(5),gallic acid(6),ellagic acid(7),kaempferol-3-O-β-rutinoside (8),β-sitosterol (9) and 7-ketologanin (10). Conclusion Compound 10 is isolated from R.chinensis for the first time. Compounds 1,2,3,4,5,6,7 and 8 are obtained from the title plant for the first time.
