Antidiabetic potential of Caesalpinia sumatrana, a medicinal herbs traditionally used by local tribe in East Kalimantan

Abstract

The aims of the research was to analyze the content of phytochemicals, to examine the antioxidant and antidiabeticpotentials of n-hexane, chloroform, ethyl acetate, and ethanol extracts of Caesalpinia sumatrana. Method to measure antioxidant capacity of sample involves the use of the free radical, 1,1-diphenyl-2-picrylhydrazyl (DPPH) which is widely used to test the ability of compounds to act as free radical. Analysis the potential of antidiabeticactivity of the extracts was determined by α-glucosidase and α-amylase inhibitory assay. Of all extracts obtained by successive maceration, ethanol maceration gave the highest extract by 2.63% of extract on the dry weigh basis. The result of phytochemicals showed that all extracts contain alkaloid and flavonoid. The highest antioxidant activity was 82.32% with IC50 value of 5.00 µg/ml obtained by ethanol extract. The results of enzyme inhibitory assay of α-glucosidase showed that ethanol extract of C. sumatrana had IC50 value 17.16 µg/mL to inhibit ɑ-glucosidase activity and IC50 value 16.78 µg/mL for ɑ-amylase. The present result displayed potential of the plant to be developed as natural antidiabetic and antioxidant agents.
