Abstract
Moringa (Moringa oleifera) has the potential to be an ingredient of superfood and biopharmaceutical because it is rich in nutrients, vitamins, and other secondary metabolites. Moringa leaves contain antioxidants to neutralize and stabilize free radicals in the body. Moringa exploration is important for the purpose of finding trees to be used as sources of superior seeds. This study aimed to obtain a Moringa tree with the highest antioxidant content. An exploration had been carried out from June to July 2021 in four cities/regencies in West Sumatra, namely Padang City, Solok City, Pesisir Selatan Regency, and Solok Selatan Regency. Coordinate data were analyzed using ArcGIS, and antioxidant activity test results were analyzed using the DPPH method. From the exploration, 36 Moringa trees were found with different characters. The results of the testing of the antioxidant activity of leaf extracts showed that there were 3 parent trees that had high antioxidant activity, marked by the lowest IC50 values, namely those in Padang City (0.17%), Solok City (0.17%), and Solok Selatan Regency (0.19%).
