Antioxidant potency of ethanolic extract of Kemuning leaves (Murraya paniculata (L) Jack ) in vitro
By using linoleic-thiocyanate method, the result suggested, that ethanolic extract of 1%; 5 % and 10 % showed antioxidant potencies and had significant different absorbances (P < 0,05).
The antioxidant potencies of ethanolic extract with different concentrations were also measured by DPPH method and the result showed that ethanolic extracts of kemuning leaves revealed the antioxidant activity with the IC50 of 126,17 µg/ml, 15 times lower than that of vitamin E (IC of 8,27 µg/ml). The antioxidant activity of kemuning leaves probably due to the flavonoid content.
