Abstract: Red pidada leaf (Sonneratia Caseolaris Engl.) contain chemical compounds including alkaloids, steroids, flavonoids and phenols. Flavonoids are compounds that can protect against UV rays. Antioxidants are compounds that are used to neutralize free radicals by donating electrons to free radical compounds. The extraction process used in this study was the maceration method using ethanol 96%. The qualitative analysis using the phytochemical screening test showed positive presence of phenol, flavonoid and tannin compounds, while the quantitative analysis used the antioxidant activity of red pidada leaf extract (Sonneratia caseolaris Engl.). Measurement of antioxidant activity was carried out using the ABTS method (2,2 azinobis (3-ethylbenzothiazoline)-6-sulfonic acid). The results showed that IC50 of ethanol extract of red pidada leaves (Sonneratia caseolaris Engl.) is 37.67 µg/mL and IC50 acidum ascorbicum is 28.42 µg/mL. So it can be concluded that the antioxidant activity of red pidada leaf extract (Sonneratia caseolaris Engl.) is strong category.
