[Chemical constituents from EtOAc fraction of Sophora dunnii].
Sixteen compounds have been isolated from the EtOAc fraction of 95% ethanolic extract of Sophora dunnii through silica gel, Sephadex LH-20 and semi-prerarative HPLC column chromatographies. Their structures were identified on the basis of NMR and MS spectra data as phaseollidin (1), L-maackiain (2), 2-(2',4'-dihidroxyphenyl)-5,6-methylenedioxy benzofuran (3), 8-demethyl-farrerol (4), liquiritigenin (5), genistein (6), 6-methylgenistein (7), 5-O-methyl genistein (8), 7,2',4'-trihydroxys-5-methoxy-isoflavanone (9), 7, 3', 4'-trihydroxy-isoflavanone (10), erythribyssin D (11), calycosin (12), trans-resveratrol (13), cis-resveratrol (14), stigmasterol (15), β-sitosterol (16). Among these, compounds 1-14 and 16 were isolated from this plant for the first time.
