Preliminary investigation of chemical composition and evaluation of antioxidant activity of Sesbania grandiflora L.

Abstract

      The major purpose of this study is to prelimiarily the phytochemical composition of the extract and evaluate the antioxidant activity of the extract using the DPPH method.The solid-liquid extraction method was employed to prepare the ethanol extract of Sesbania seed. After the steps of extraction with 96 % of ethanol, exhaustion for 24 hours, solvent removal by vaccuum evaporation, a total of 22 g of ethanol extract was obtained from 500 g of dry Sesbania seed powder. The research results provide some previously unexplored information about sesbania seeds, helping to identify its potential in prevention, treatment, and further enriching the treasure trove of traditional Vietnamese herbal medicine. Based on the obtained results, the study has identified a series of important compounds in Sesbania seeds and demonstrated the potent antioxidant activity of ethanol extract, enhancing the role of Sesbania seeds in life.
