  Background and Objective: Some metabolites derived from plants have strong potential for free radical cleaning. The aim of this study was to determine and compare the antioxidant and antiradical properties of leaf extract of mangrove, Avicennia marina, and two red and brown algae (Gracilaria corticata and Cystoserriaceae myrica),  from coastal areas of Persian Gulf in Booshehr province. Method: Extraction of two species of brown and red algae and mangrove was done by soaking method from coast of the Persian Gulf, and also antioxidant activities of extracts of added species were recorded using DPPH and RP tests. Findings: According to the DPPH test, the highest antioxidant activity was observed in ethanol extract of mangrove leave and the lowest was observed in brown algae C. myrica. The highest antioxidant activity by RP test was observed in methanol extract of brown algae C. myrica and the lowest was observed in ethanol extract of mangrove leave. There were also significant differences (sig<0.05) between methanol extract of C. myrica and other prepared extracts according to the RP test. Conclusion: In this study, the highest anti-oxidant activity was found in methanolic extract of algae C. myrica (by RP test) and in leaf extract (etanolic) of mangrove A. marina (by DPPH test).
