ANTIOXIDANT ACTIVITY OF Rhizophora mucronata MANGROVE FRUIT IN LANGGE VILLAGE, ANGGREK DISTRICT, GORONTALO REGENCY NORTH

Abstract

Rhizophora mucronata is one of the many mangrove plants found on the coasts of countries in Asia, including Indonesia. The fruit of this plant is widely used as medicine and food and is believed to have potential as a source of antioxidants. The purpose of this study was to study the antioxidant activity of R. mucronata fruit with a diameter of 2–3 cm using different solvents, namely ethanol (food grade) and water (Aquades). The antioxidant activity of mangrove fruit was tested using the DPPH (1,1-diphenyl-2-picrylhydrazil) method. The results of the analysis showed that R. mucronata fruit extracted using water (aquades) had an IC50 value of 40.54 ppm while using ethanol (food grade) the IC50 value was 18.94 ppm.
