Abstract: Bauhinia purpurea leaves yield two new dimeric flavonoids namely bis [3',4'-dihydroxy-6-methoxy-7,8-furano-5',6'-mono­methyl­allyloxy ]-5-C-5-biflavonyl 1 and (4'-hydroxy-7-methyl 3-C- -L-rhamnopyranosyl)-5-C-5- (4'-hydroxy-7-methyl-3-C--D-glucopyranosyl) biflavonoid 2 with protein precipitating capacity 214.4 and 199.24 g BSA /g, respectively. Their identity has been established on basis of spectroscopic data and chemical reactions.
