Uji Aktivitas Antioksidan dari Ekstrak Etanol Daun Nangka (Artocarpus heterophyllus) dengan Metode DPPH

Abstract

Background: Jackfruit (Artocarpus heterophyllus), a plant belonging to the Moraceae family, is one of the fruits that has good benefits for humans. Jackfruit leaf parts can be used as natural antioxidants because they contain secondary metabolites. DPPH (1,1-diphenyl-2-picrylhydrazyl) is often used to assess the antioxidant activity of several extracts or natural ingredients so that it can evaluate the antioxidant potential of reducing free radicals. Objective: This study aims to determine the antioxidant activity of an ethanol extract of jackfruit (Artocarus heterophyllus) leaves using the DPPH method. Method: Testing of the antioxidant activity of the ethanol extract of jackfruit leaves was carried out using the DPPH method. Results: Jackfruit leaf ethanol extract has an IC50 antioxidant activity of 57.1552 with a regression equation of Y = 0.7466x + 7.3279 and a correlation coefficient of R2 = 0,9779. Conclusion: The IC50 antioxidant activity obtained from the ethanol extract of jackfruit leaves is 57.1552, which is categorized as strong.
