AKTIVITAS ANTIOKSIDAN EKSTRAK METANOL BUAH PAPRIKA HIJAU (Capsicum annum L.)

Abstract

Green paprica (Capsicum annum L.) is one of fruits which have contain
–carotene, vitamin E and vitamin C, which have antioxidant activity. The aim of this
research is to know an antioxidant capacity of green paprica. An analysis of the
antioxidant activity of this research used radical scavenging DPPH
(1,1–difenil–2–pikrilhidrazil) method. The sample was preparated with maceration for
4 days using methanol as the solvent. Crude extract was evaluated qualitatively using
0,4 mM DPPH reagent. This result of qualitative analysis showed that green paprica
have an antioxidant activity. Then, absorbance was measured using UV–Vis
spectrophotometer at wavelength of 517 nm. The result of this analysis obtained EC50
value of green paprica was 0,3399 ± 0,01408 mg/ml.
