Abstract

Indonesia is one of the countries rich in natural resources, especially plant diversity. This plant diversity includes various types of plants that have the potential as traditional medicine. Types of plants that can be used as traditional medicine are useful for curing various diseases in the community and can be used as raw materials for medicine. In the Ogan Komering Ulu Timur (OKU Timur) district there are 20 sub-districts but only 2 sub-districts are used as plant exploration areas that are used as observation objects, namely Bunga Mayang and Martapura. Used in traditional medicine by the Javanese people in Buay Madang Timur, OKU Timur. Based on research conducted by previous researchers, the researchers aim to determine the chemical content and antioxidant activity of the dadap ayam plant leaves. The dadap ayam plant is a plant used in traditional medicine by the Javanese people in Buay Madang Timur, OKU Timur and is known as a herbal plant based on previous research journals. The study of antioxidant activity of dadap ayam leaves was conducted from October 2024 to March 2025. The results of this study obtained strong antioxidant activity in the thick extract of dadap ayam leaves (Erythrina variegata L.) obtained in the N-Hexane fraction, which was 5.4306 ppm, and the ethyl acetate fraction, which was 17.819 ppm. The methanol-water fraction was not active in antioxidant activity. The groups of pure compounds that have antioxidant activity obtained in dadap ayam leaf samples are the terpenoid group (N1), phenol group (N2 and E1), steroid group (N3) and flavonoid group (N4, and E4). Pure compounds obtained from dadap ayam leaf samples have very strong, strong and moderate antioxidant activity. Pure compounds with the terpenoid group (N1) obtained an IC50 value of 58.49 ppm. The phenol compound group (N2 and E1) obtained an IC50 value of (17.12 ppm and 100.15 ppm). Meanwhile, the steroid compound group (N3) obtained an IC50 value of (65.59 ppm) and the flavonoid compound group (N4 and E4) obtained an IC50 value of (10.29 ppm and 25.09 ppm).
