Eleven new secondary metabolites (1-11), together with two known flavanones (12 and 13) and five known bibenzyls (14-18), were isolated from the root extract of Bauhinia purpurea. New compounds include eight dihydrodibenzoxepins (1-8), a dihydrobenzofuran (9), a novel spirochromane-2,1'-hexenedione (10), and a new bibenzyl (11). Antimycobacterial, antimalarial, antifungal, cytotoxic, and anti-inflammatory activities of the isolated compounds are reported, and biosynthetic pathways of these compounds are also discussed.
