Abstract
Kunyit asam and sinom are the kinds of Indonesian traditional beverage, which have a
potency to be developed as a source of antioxidant. The research was carried out to determine the
antioxidant capacity of kunyit asam and sinom beverages and their inhibition activity against ?-glucosidase. Antioxidant capacity was analyzed using DPPH (1,1-diphenyl-2-picrylhydrazyl) method.
Regression method was used to find out the correlation between the antioxidant capacity of the
beverage and percentage of inhibited ?-glucosidase The result showed that antioxidant capacity of
both beverages correlated significantly with the percentage of ?-glucosidase inhibition. Antioxidant
capacity of kunyit asam beverage was 2.04 mg GAEAC/g (2,042 ppm) and its IC50 was about 146.48
ppm against the activity of ?-glucosidase. Sinom beverage had antioxidant capacity of 1.88 mg
GAEAC/g (1,881 ppm) and its IC50 was 231.37 ppm.
Keywords : kunyit asam, sinom, antioxidant, inhibition, and ?-glucosidase
