Areca vestiaria, Antioxidant, DPPH (1,1-diphenyl-2-picrylhydrazyl).Abstrak
Pinang Yaki with the Latin name Areca vestiaria is a type of palm tree originating from eastern Indonesia, especially Sulawesi. Antioxidants are compounds that are known to ward off the effects of free radicals, where free radicals are defined as atoms or molecules that are unstable. This study aims to determine the antioxidant activity of the ethanol extract produced by Areca vestiaria fruit using the DPPH (1,1-diphenyl-2-picrylhydrazyl) method. This research is a laboratory experiment by testing the ethanol extract of Areca vestiaria fruit using the DPPH (1,1-diphenyl-2-picrylhydrazyl) method. The results of the data analysis of the % Inhibition values were 40,60% (25 ppm), 42,18% (50 ppm), 46,79% (75 ppm), 47,75% (100 ppm), 54,48% (125 ppm) and the IC50 value is 102,31 µg/mL. This shows that the Areca vestiaria fruit samples obtained from the slopes of Mount Mahawu, North Tomohon District, Tomohon City, have antioxidant activity.
