Kadar Total Fenolik Ekstrak Etanol Jarak Pagar (Jatropha curcas. L) yang Berpotensi sebagai Antioksidan

Abstract

This study aims to determine the total phenolic content of Jatropha curcas leaf extract and evaluate its potential as an antioxidant. Fresh Jatropha curcas leaves were obtained from Ternate City and extracted using 96% ethanol through the maceration process. The total phenolic content in the extract was determined using the UV-Vis spectrophotometric method with the Folin-Ciocalteu reagent and gallic acid as the standard of comparison. The results showed that the ethanol extract of Jatropha leaves had a total phenolic content of 6,780 mg GAE/g. The resulting extract has thick characteristics, is green in color, and smells distinctive. The extraction yield of 19.46% shows the efficiency of the extraction method used. In conclusion, jatropha leaves contain high phenolic compounds, which support their potential as a source of natural antioxidants. This potential can be utilized in the development of health and pharmaceutical products, both in the form of traditional and modern medicines. This study provides valuable information related to the phenolic content of Jatropha leaves and supports its wider utilization in the health sector.
