Identification of Antioxidant Compounds Structure Large-Leafed Mangrove (Bruguiera gymnorrhiza) Fruit

Antioxidants are compounds that can inhibit or prevent the oxidation of the easily oxidized substrate. One of the plants as a potential source of bioactive compounds and antioxidant activity is large-leafed mangrove (Bruguiera gymnorrhiza). This plant is commonly found in the Pacific region of Southeast Asia, Ryukyu Islands, Micronesia and Polynesia (Samoa) to subtropical regions of Australia and has been used by the society. This study aimed to determine the bioactive compounds structure of large-leafed mangrove has the highest antioxidant activity. The compound structure prediction was done by Nuclear Magnetic Resonance (NMR). The compound structure in the selected antioxidant fractions are flavonol, glikosilfalvon and flavon. Those three compounds are flavonoid compound which has a great role as the one that has antioxidant activity in large-leafed mangrove fruit.
