Scaevola taccada is a coastal plant. This plant lives in gravel sandy soil and can prevent erosion that occurs on the beach. In the Riau Islands, it is still very rare, not even a few do not know the benefits of this plant, especially the fruit. The study aimed to determine the antioxidant activity of young, old, and mixed fruit extracts of S. taccada using the DPPH method which was stated to be IC50. The research methods include extraction, phytochemical test, antioxidant test and vitamin C test. The yield of pulp and water extract of young fruit was 55% and 41.4%, pulp and water extract of old fruit was 33.33% and 42.9%, respectively. Phytochemical bioactive analysis was found to be positive for saponin parameters, indicated by the presence of stable foam for 30 minutes. Antioxidant activity using DPPH method obtained IC50 19,524 young fruit extract, IC50 50,664 old fruit extract, and IC50 35.518 mixed fruit. Analysis of Vitamin C in old S. taccada fruit yielded 5.28 mg, young fruit yielded 20.24 mg, and mixed fruit yielded 35.20 mg. The conclusion of this study is the presence of antioxidants and vitamin C in Scaevola taccada fruit.
