Abstract:
OBJECTIVETo investigate the chemical constituents in 95% alcohol extract of Solanum lyratum.
METHODThe compounds were isolated by column chromatography over silica gel, and purified by Sephadex LH-20 column chromatography and preparative TLC. The structures were elucidated on the basis of physicochemical properties and spectral data.
RESULTEleven compounds were isolated and identified as: formononetin (1), vanillic acid (2), genistein (3), apigenin (4), N-trans-feruloyltyramine (5), N-p-coumaroyltyramine (6), daidzein (7), caffeic aicd (8), protocatechuic acid (9), daidzin (10), and N-trans-feruloyl-3-methyldopamine (11).
CONCLUSIONFor the first time, compound 11 was separated from Solanaceae plant, and compounds 5 and 10 were isolated from Solanum, and compounds 1, 3, 4, 7 and 9 were obtained from this plant for the first time.
