Chemical investigation of the leaves of Solanum sordidum Sendtn., Solanaceae, resulted in the isolation and identifi cation of sitosterol, stigmasterol, 3β-
and N-trans-feruloyltyramine.The structures of these compounds were established by analysis of 1D and 2D NMR spectrometric data and comparison with data in the literature. The evaluation of antioxidant activity showed an IC50 of 159.5 ppm for the chloroformic fraction and IC50 of 77.5 ppm for the hydromethanolic fraction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
