Bruguiera gymnorrhiza is one of the mangrove species that a source of antioxidants. Antioxidant substances are able to protect cells from oxidative stress and other related diseases. This study aimed to evaluate the chemical profiles, predicted biological activity, and antioxidant activity of the B. gymnoriza fruit extracts. The research methods included sampling, extraction (maceration with MeOH:DCM), identification of chemical profiles (GCMS spectra analysis), assaying for computational analysis (PASS server and ADMET), antioxidants (DPPH radical scavenging), and total phenolic content (FolinCiocalteu). Bruguiera gymnorrhiza fruits was collected from Central Sulawesi, Indonesia. The chemical profiles detected in the B. gymnorrhiza fruit extracts, namely isopimaradiene (64.20%); 4-(2-Aminopropyl) phenol (19.06%); dimethylaminodimethylphosphene oxide (9.40%); 3-amino-2-benzylbutanoic acid (5.46%); and 1,4- dideuteriooctane (1.89%). PASS server analysis showed that the five compounds detected from B. gymnorrhiza fruit have the potential as an NF-E2-related factor (Nrf2) stimulant and oxygen scavenger. The ADMET analysis results indicated that B. gymnorrhiza fruits could be developed as folk medicine and nutraceutical products.
