摘要：
Investigation of the roots of Lotus polyphyllos Clarke resulted in the isolation of two new isoflavone derivatives; 4'-O-methylerythrinin C ( 3) and 4'-O-methyl-2 ''-hydroxydihydroalpinumisoflavone ( 4). In addition, the three known isoflavone derivatives 4'-O-methylalpinumisoflavone ( 1) lupinalbin F ( 5), 4',7-dimethoxy-5-hydroxyisoflavone ( 6), and the phenylpropanoid ester tetracosyl p-coumarate ( 2) were also identified. The structures were determined from spectroscopic data.
