title: [Isoflavones and flavans from Millettia nitida var. hirsutissima].
abstract: The current study to separate and identify constituents from Millettia nitida var. hirsutissima. The compounds from Millettia nitida var. hirsutissima were isolated by means of various chromatographic techniques such as column chromatography over ODS and Sephadex LH-20, preparative HPLC, and the structures of these isolated compounds were identified through spectroscopic analyses. Nine isoflavonoids and two flavans were isolated and identified as 5-O-methy genistein (1), 7-hydroxy-3',4'-dimethoxyisoflavone (2), ononin (3), catechin (4), formononetin (5), genistein (6), calycosin (7), (-)-gallocatechin (8), sissotrin (9), wistin (10), daidzin (11). Compounds 1, 2, 9 are obtained from the genus Millettia for the first time,and compounds 4, 8 are isolated from this plant for the first time.
