title: A new biflavonoid from Ochna beddomei.
abstract: A new biflavonoid, 2,3-dihydroochnaflavone 7,4',7"-tri-O-methyl ether (1) together with two known biflavonoids namely, 2,3-dihydroochnaflavone (2) and ochnaflavone (3) were isolated from the stem bark of Ochna beddomei. The structures were determined by means of spectral and chemical studies.
