Abstract:

In India, the prevalence of diabetes mellitus is on the increase and needs to be addressed appropriately. In this study area, herbal remedies are considered convenient for management of Type 2 diabetes with postprandial hyperglycemia due to their traditional acceptability and availability, low costs, lesser side effects. Comparative evaluation of alpha amylase inhibitory activities of selected plants extracts. Kharagpur is situated in the Midnapur West district of West Bengal in India. In this district, diabetes prevalence is comparatively high. Ten common plants in IIT Kharagpur 1 Block namely, Acalypha indica, Allium cepa, Allium sativum, Azadirachta indica, Musa sapientum, Mangifera indica, Murraya, Ocimum sanctum, Phyllanthus amarus and Tinospora cordifolia were tested for their alpha amylase inhibitory activities to establish anti-diabetic potentials. The plant extracts were prepared sequentially with petroleum ether, hexane, chloroform, ethanol and aqueous. The extracts obtained were subjected to in vitro alpha amylase inhibitory assay using starch azure as a substrate and porcine pancreatic amylase as the enzyme. Statistical difference and linear regression analysis were performed by using Graphpad prism 5 statistical software. Ethanol extracts of Mangifera indica, Azadirachta indica and petroleum ether extract of Murraya koenigii (at a concentrations 10-100μg/ml) showed maximum percentage inhibition on alpha amylase activity with an IC 50 value of 37.86 ± 0.32μg/ml, 62.99 ± 1.20μg/ml and 59.0 ± 0.51μg/ml respectively when compared with acarbose (IC 50 value 83.33 ± 0.75μg/ml). The results showing that Mangifera indica, Azadirachta indica and Murraya koenigii might be effective in lowering post prandial hyperglycemia.
