Lindur are mangrove plants that has been widely used as drug, yet informations on potential drug compounds and antioxidants contained in lindur were still limited. This study were determined to determine the chemical composition, bioactive components, antioxidant activity, and total phenol contained in lindur. The result showed that lindur fresh leaves had a moisture content, ash, fat, protein, and crude fiber of 54.91%, 4.49%, 1.87%, 4.45%, and 8.67%; respectively. Lindur dried leaves had water, ash, fat, protein, and crude fiber content of 9.79%, 8.19%, 3.90%, 9.78%; and 18.05%, respectively. The methanol extract had the highest yield (15,79%) compared to the ethyl acetate extract (2.85%), and n-hexane (1.53%). Phytochemical analysis showed the bioactive components of n-hexane extract (phenol steroids and hydroquinone); ethyl acetate extract (steroids, hydroquinone phenols, flavonoids, saponins) and methanol extract (steroids, hydroquinone phenols, flavonoids, tannins, saponins). Methanol extract showed the highest antioxidant activity with IC₅₀ values of 81.11 ppm, while the n-hexane extract showed the lowest activity with IC₅₀ values of 815.67 ppm. Total phenolic extracts of n-hexane, ethyl acetate, and methanol, were 12.41, 97.57, and 30.07 mg GAE/ g extract, respectively.
