Eugenia jambolana and Aegle marmelos are used extensively in the indigenous system of medicine as an anti-diabetic agent. The current investigation focuses on the serum insulin augmentation, anti-hyperglycemic and anti-hyperlipidemic property of a combined aqueous extracts of E.jambolana and A.marmelos (EA) on alloxan induced diabetic rats. The diabetes induced animals were fed with plant extracts at the increasing dosage of 200mg, 300mg and 400mg of body wt. The combined plant extracts administrated animals revealed a significant (P lessThan 0.001) increment of serum insulin levels, higher reduction in hyperglycemia and hyperlipidemia when compared to the diabetic control rats (P lessThan 0.001).
