Antioxidant Activity and Toxicity Test on Mangrove (Rhizophora Apiculata) from Banyuasin Waters, South Sumatra

Antioxidant Activity and Toxicity Test on Mangrove (Rhizophora Apiculata) fromBanyuasin Waters, South Sumatra determine the content of secondary metabolites [3].According to Akasia et al. [4], R. apiculata contained phenolic compounds, alkaloids, flavonoids, tannins, saponins and steroids.However, the metabolite compounds contained in R. apiculata mangrove parts such as stems, roots, and leaves have different concentrations.Antioxidants are compounds that can inhibit free radical reactions in the body [5].Free radicals are molecular atoms that have unpaired electrons and if the molecular atoms present in high amounts in the body, these can cause stress, cancer, diabetes and inflammation [6].Free radicals can be formed either naturally in the body through normal metabolic processes (metabolic waste) or from external factors such as food, X-rays, air pollutants, and cigarette smoking.The body has the ability to ward off free radicals in small amounts but not in large quantities.One of the methods used to measure the level of antioxidants in samples is the DPPH method.Toxicity is a qualitative term whether there is a damage or not depending on the amount of toxic active compounds absorbed.The results obtained from the toxicity test using the BSLT method have been proven to have a positive correlation with the toxicity of anticancer compounds [3].The BSLT method uses A. salina as the observed test object.
