The Ayurvedic Pharmacopoeia of India recommends the dried fruit in chlorosis, common cold, rhinitis and obstinate skin diseases.

The activity of the drug is attributed to the presence of saponins which occur to the extent of 2 3% in fresh fruits and about 10% in dried whole fruit. The saponins are concentrated mostly in the pulp. A mixture of two saponins, viz. randialic or neutral sap onin and randialic acid or acid sap onin has been isolated from the pulp. On complete hydrolysis both the saponins yield oleanolic acid as sapogenin. Ursosaponin, isolated from the ethanolic extract of the dried whole fruit, gave ursolic acid and glucose. Randianin, isolated from the fruit, gave a haemolytic triterpenoid saponin. In experimental animals, the drug

caused haemolysis both in vitro and in vivo. Crude saponin fraction showed haemolytic, molluscidal and immunostimulating activities.

Oleanolic acid 3-glucoside, isolated from the seed, exhibited anti-arthritic activity in exudative and proliferative phases of inflammation in rats.
