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

摘要

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.
