A Review: Testing Antioxidant Activity on Kawista Plants (Limonia acidissima L.) in Indonesia

Abstract

BACKGROUND: Antioxidants are natural ingredients that can block the oxidation process of free radicals that enter the body so that damage to body cells can be prevented. Kawista plants are one of the plants that have antioxidant activity. AIM: This article review aims to determine the compounds that have antioxidant activity found in Kawista plants, the method used in testing antioxidants on Kawista plants, and the IC50 value found in antioxidant testing on Kawista plants. METHODS: The method used in this study is the Population, Intervention, Control, and Outcome method through inclusion and exclusion criteria using the keywords “Antioxidant activity of Limonia acidissima,” “Antioxidant activity of Feronia limonia,” “Antioxidant activity of Kawista,” “Testing Antioxidants in L. acidissima,” and “L. acidissima” with databases used for literature searches. RESULTS: This review shows that Kawista plants have antioxidant activity of various compounds based on the test method used. CONCLUSION: Compounds in Kawista plants that have antioxidant activity are phenols, especially phenolic acids, flavonoids, flavonols, triterpenoids, saponins, tannins, terpenes, steroids, alkaloids, and glycosides. Kawista plant activity tested had IC50 with an average value of very strong (16.45 g/mL), strong (77.85 g/mL), moderate (135.02 g/mL), weak (196.67 g/mL), and very weak (751.89 g/mL).
