UJI ANTIOKSIDAN DENGAN METODE DPPH DARI EKSTRAK JAMUR ENDOFIT Botryosphaeria rhodina

Abstract

Botryosphaeria rhodina is one of the endophytic fungi that can be found in areas with tropical and subtropical climates. Several studies have reported that this endophytic fungus has biological activities such as antimicrobial and antiseptic. However, not many studies have reported its antioxidant activity. The goal of this study was to determine the antioxidant activity of n-hexane extract and methanol extract of B. rhodina. Based on the antioxidant test using the DPPH method, it showed that the n-hexane extract had a very weak antioxidant activity with value of IC50 > 1000 ppm, while the methanol extract with an IC50 of 363.68 ppm showed weak antioxidant activity when compared to ascorbic acid but has the potential as an antioxidant. antioxidant-producing substances.
