<p>Plants lindur (Bruguiera gymnorrhiza) is one of the plants that have a potential as<br />a source of bioactive compounds for the antioxidant. This study aimed to determine the<br />chemical composition, bioactive compound and determine antioxidant activity of leaves,<br />bark and roots of plants lindur (B. gymnorrhiza). This research was conducted through<br />several stages proximate test, stratified extraction, phytochemical test, and antioxidant<br />activity test with DPPH. The highest yield value resulting by ethanol extract of the leaves<br />is 12,85 % and the lowest was produced by n-hexane root extract that is 0,18 %. The leaves<br />contain high levels of protein, fat, and water which is the higher of the two parts from the<br />other samples. Bark containing ash content (4,12%) and carbohydrates (46,02%). Root has<br />the highest levels of carbohydrates that is 25,91 %. Bioactive components were detected on<br />ethanol and ethyl acetate extracts of the leaves are flavonoids, tannins, phenols, saponins,<br />steroids and tritepenoid. Bark extract ethanol, ethyl acetate and ethanol root bark has<br />bioactive components there are flavonoids, tannins, phenols, saponins, and tritepenoid. </p><p>Ethyl acetate extract of the roots only have bioactive components there are flavonoids,<br />phenols, saponins, and triterpenoids. The potential antioxidant activity produced from<br />ethyl acetate extracts of bark lindur with IC50 values is 14,21 ppm.<br />Keywords: Antioxidants, phytochemicals, roots, ethanol, Bruguiera gymnorrhiza</p>
