Abstract

Antioxidants are compounds that can inhibit or prevent oxidation reactions, which are the result of chemical reactions and metabolic processes that occur in the body. Enhalus acoroides is a type of seagrass found in Indonesian waters, generally living in sandy sediments with high bioturbation. Lamun has good nutrition and fiber so that it can be a source of food and medicine. The aim of this study was to examine the antioxidant activity of the seagrass extract Enhalus acoroides against ABTS radicals (2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid). The results of the study of seagrass extract using ethanol solvents had a very strong antioxidant category ie 38,008 µg /ml, the smaller the absorbance value, the higher the inhibitory value in which the antioxidant activity of the extract is higher, but when compared with the routine compound control of 0.500 µg /ml, seagrass ethanol extract is still lower.

Abstract

The black mulberry (Morus nigra) plant has been widely developed for its bioactivity as natural medicine. This study evaluated plant extracts' total phenolic and flavonoid content and their correlation to M. nigra stem's antioxidant activity and toxicity. Dry powder from the M. nigra stem was extracted by maceration with 96% ethanol to obtain a thick extract (TE) and fractionated using hexane (HF), ethyl acetate (EAF), and ethanol-aqueous (EF). The samples were analyzed for a compound using reagents and the determination of total phenolic and flavonoid content. The samples were evaluated for antioxidant activity using several parameters and their cytotoxic effects using the BSLT method. Identification of compounds in EAF was confirmed to contain phenolic, flavonoids, alkaloids, saponins, tannins, steroids, and terpenoids. EAF showed higher phenolic and flavonoid content than others. The evaluation of antioxidant activity showed that extracts and fractions from M. nigra stems showed the ability to reduce ions and free radicals. EF sample has activity in reducing Mo (IV) ion by TAC method of 98.82±0.53 µM/mg, indicating substantial antioxidant capacity. In addition, EAF samples showed potential activity in reducing DPPH, hydroxyl, and peroxide radicals in the β-carotene bleaching method with IC50 values of 12.13, 42.06, and 57.6 µg/mL, respectively. Similar activity was also seen in the cytotoxic effect of a robust EAF sample with an LC50 value of 16.31 µg/mL. The results show that EAF can be developed as a raw material for traditional medicine as an antioxidant and anticancer candidate with a significant flavonoid and phenolics content.
