Antidiabetic potential of aqueous and alcoholic leaf extracts of Pithecellobium dulce

Ethanolic and aqueous leaf extract of Pithecellobium dulce was studied for its antidiabetic activity using streptozotocin-induced diabetic model in rats. The aqueous extract showed significant activity (P<0.01) than the alcoholic extract at the tested dose level which was comparable to glibenclamide, a standard antidiabetic drug. HPTLC fingerprinting profile of the aqueous extract was also developed which would serve as reference standard for quality control of this extract.
