Abstract


Objective: The aim of the present study was to evaluate the alpha (α)-amylase and alpha (α)-glucosidase inhibitory activities and in vitro antioxidant activities of the 80 % aqueous ethanol extracts of Tinosporasinensis Lour (Merr.).

Methods: The 80% aq. ethanol extract of the plant was prepared. The plant extract was examined for its antioxidant activity by using free radical 1,1-diphenyl-2-picryl hydrazyl (DPPH) scavenging method, ABTS radical scavenging ability, reducing power capacity, estimation of total phenolic content, flavonoid content and flavonol content. Different concentrations (2, 4, 8,10and 15 μg/ml) of the extract was subjected to α-amylase inhibitory and α-glucosidase inhibitory activities and IC50were calculated.

Results: The study revealed that the different concentrations of the plant extract possessed a very good amount of total phenolics, flavonoid and flavonol and exhibited potent radical scavenging activity using DPPH and ABTS as a substrate. The ethanol extracts exhibited significant α-amylase and α-glucosidase inhibitory activities with an IC50 value1.093µg and 1.04µg dry extract respectively and well compared with standard acarbose drug.

Conclusion: Thus, it could be concluded that due to the presence of antioxidant components the plant extracts could be used for the treatment of hyperglycemia, diabetes and the related condition of oxidative stress. This knowledge will be useful in finding more potent components from the natural resources for the clinical development of antidiabetic therapeutics.
