The fruit is a rich source of ascorbic acid-Vitamin C. Ten gms of fresh fruits contain 600-900 mg of Vitamin C3. The small fruit variant contains more Vitamin C than the large variant. According to recent work fruits lose Vitamin C more when dried in the sun than in the shade. Ellagic acid is present in bark.

Alcoholic extract of the plant (1 gm/kg) has shown an increase in the cardiac glycogen and a decrease in serum GOT, GPT and LDH in isoprotenol pretreated rats, suggesting a cardio- protective action.
