An antimicrobial constituent, mas- linic acid, alongwith gallic acid and pyrogallol, has been isolated from the leaves. Alcoholic extract of the leaves completely inhibited Micrococcus pyo- genes, but was inactive against E. coli. The aqueous extract, however, showed partial inhibition against E. coli. The aqueous extract also showed potent inhibitory activity towards lens aldose re- ductase, which plays an important role in the management of diabetic complications. The activity is attributed to a flavonoid, isoscutelarein.

Bixin, the main constituent of seed coat, shows cytostatic effect on the growth of human lymphoma cells. Bixin also has a hyperglycaemic effect and may disturb blood glucose control.
