EFFECT OF COMBINATION OF 2 AQUEOUS LEAF EXTRACTS ON DIABETES MELLITUS. EFFECT OF COMBINATION OF AQUEOUS LEAF EXTRACTS OF PSIDIUM GUAJAVA LINN AND MORINGA OLEIFERA LAM ON DIABETES MELLITUS

      Аннотация: Objective: To determine the anti-diabetic activity of combined aqueous extracts (1:1mixture) of dry leaves of Psidium guajava linn and Moringa oleifera lam as well as to compare the anti-diabetic activity of these plants by in vitro methods.Methods: In vitro alpha amylase inhibitory assay was performed on porcine alpha amylase and the absorbance was measured at 540nm using a microplate reader and glucose diffusion inhibitory assay using dialysis membrane. Acarbose was used as the standard in the above mentioned methods.Conclusion: The combined extract of the leaves of the 2 plants was found to be more effective than individual plant extracts against diabetes. On comparison of two plants Psidium guajava was found to be more active against diabetes than Moringa oleifera. Also the potentiation effect shown by the combination of extract may be due to synergistic effect of the phytochemical constituents. As the 1:1 mixture of the aqueous extract is found to be more active, the combination of the two plants can be used to formulate drugs for treating diabetes.
