Seed extract—hypoglycaemic.Powdered aerial parts prevented elevation of SGOP, SGPT and bilirubin levels.Hepatoprotective effect of aerial parts was evaluated against (+)-galac- tosamine-induced and carbon tetra- chloride-induced hepatotoxicity in rats.The leaves contain rutin and rote- noids (0.65-0.80% on dry basis). Rote- noid content is highest in the seed (1.60-1.80%).The leaves also contain a triterpe- noid, lupeol, and beta-sitosterol.Seeds contain a diketone-pongamol; a dimethylchromene flavanone iso- lonchocarpin; furanoflavones karan- jin and kanjone; a flavanone purpurin; and sitosterol.
