Rhamnocitrin can enhance the immune function, improve the formation of spleen cells of mice serum hemolysin of chicken red blood cell immune.

In cataract, the oxidation-antioxidant equilibrium shift more towards oxidative stress. Accordingly, antioxidants could prove potential anticataract agents. Rhamnocitrin, a flavonoid, possess strong antioxidant effects; can be used effectively to manage the cataract. Therefore, anticataract activity of Rhamnocitrin (10, 20, 40 and 80 μg), isolated from Bauhinia variegata (Leguminosae) stem bark, was studied in ovine and chick embryo lens model. It showed a significant protection against cloudiness in lenses induced by hydrogen peroxide and hydrocortisone in a dose dependent manner.
