RESUMO
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.
RESUMO
AIM: To investigate the constituents of the effective fractions from Shenshao Xinxin Prescription(Radix et rhizoma ginseng;Radix paeoniae rubra;Radix puerariae lobatae). METHODS: The compounds were isolated by column chromatography on silica gel,polyamide,sephadex gel and their structures were determined on the basis of their spectroscopic evidence including UV,FAB-MS and NMR data. RESULTS: Eight compounds had been isolated and identified as daidzein,4′-O-methyl-daidzin,genistin,PG-3,puerarin,paeoniflorin,daidzein 8-C-Apiosyl(1→6) glucoside,4′,7-diglucoside. CONCLUSION: The compounds obtained were the alcohol-soluble compounds from Shenshao Xinxin Prescription.
