Abstract

Antioxidants are compounds that can stabilize free radicals in the body. Free radicals are highly reactive molecules because they have unpaired electrons so they can interact with body cell molecules. Kasturi mango leaves contain flavonoids, saponins, terpenoids, and tannins which can be used as antioxidants. This study aims to determine the antioxidant activity of n-hexane, ethyl acetate, water and methanol extracts of kasturi mango leaves, and to determine the greatest antioxidant activity between n-hexane, ethyl acetate, water and methanol extract of kasturi mango leaves. Kasturi mango leaf (Mangifera casturi Kosterm.) was extracted using maceration method with methanol followed by fractionation using n-hexane and ethyl acetate solvents. Test of antioxidant activity to DPPH radical was done to nhexane, ethyl acetate, air, and methanol extracts of kasturi mango leaf. The test results of antioxidant activity which expressed by IC50 value to the n-hexane, ethyl acetat, water fraction, and methanol extract of kasturi mango leaf were 219,42 ppm, 68,63 ppm, 132,57 ppm, and 94,48 ppm; respectively. The greatest antioxidant activity was ethyl acetate fraction. Keywords: Kasturi mango leaf, antioxidant, methanol extract, DPPH
