N2 - antioxidant activity of Cincau Perdu leaves extract (Premna oblongata Miq.) using 1-Diphenyl-2-picrylhydrazyl (DPPH) methods. P. oblongata leaves was extracted using n-hexane, ethylacetate and methanol. It was found that methanol extract has the highest activity with IC50 value 20.01 μg/mL. The extract with highest antioxidant activity were fractionated with accelerated column chromatography and were earned 6 combination fractions. The antioxidant activity of each combination fractions were tested by DPPH methods. Fraction-5 showed the highest activity as antioxidant with IC50 23.51 μg/mL. The compounds of the active fractions were flavonoid, glikon, saponin and tannin.
