摘要：

Chemical investigation of the leaves of Solanum sordidum Sendtn., Solanaceae, resulted in the isolation and identification of sitosterol, stigmasterol, 3 beta-O-beta-glycopyranosyl stigmasterol, 3 beta-O-beta-glycopyranosyl sitosterol, kaempferol-3-O-alpha-rhamnopyranosyl-(1-6)-alpha-glycopyranoside, rutin, 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.
