Flavonoids from Millettia nitida var. hirsutissima.
From the stems of Millettia nitida var. hirsutissima, three new isoflavone glycosides, formononetin 7-O-beta-D-(6''-ethylmalonyl)-glucopyranoside (1, hirsutissimiside A), 5-O-methyl genistein 7-O-alpha-L-rhamnopyranosyl-(1-->6)-beta-D-glucopyranoside (3, hirsutissimiside B), retusin 7,8-di-O-beta-D-glucopyranoside (4, hirsutissimiside C) and two known isoflavone glycosides (2) and (5) have been isolated. The structures of the compounds were determined by spectroscopic and chemical means.
