title: [Chemical constituents of stem barks of Mucuna birdwoodiana].
abstract: Eleven compounds were isolated from the stem bark of Mucuna birdwoodiana. Their structures were elucidated by various spectral analyses and identified as 3'-methoxycoumestrol(1), formononetin(2), genisten(3), 8-0-methylretusin(4), 7, 3'dihydroxy-5'-methoxyisoflavone(5), chrysophanol(6), syringaresinol(7), epifriedelanol(8), lupeol(9), respectively.
