Abstract

A new coumaronochromone derivative, sophorophenolone (1), along with 13 known compounds, l-maackiain (2), medicagol (3), 7-O-methylpseudobaptigenin (4), pseudobaptigenin (5), 7,3'-di-O-methylorobol (6), genistein (7), prunetin (8), daidzein (9), formononetin (10), Di-O-methyldaidzein (11), quercetin (12), kaempferol (13) and isorhamnetin (14) were isolated from pericarps of Sophorajaponica L. The structure of compound 1 was established by UV, IR, MS, and one-dimensional and two-dimensional NMR spectroscopy, including DEPT, NOESY, 1H-1H COSY, HMQC, and HMBC experiments.
