Abstract

The purpose of present study is to investigate the chemical composition of Senecio oleosus, since in a previous study, pyrrolizidine alkaloids were putatively identified in extracts of this species. The preliminary analysis using 1H NMR and HPLC-DAD techniques showed the presence of pyrrolizidine alkaloids in the ethyl acetate and hydromethanolic fractions. Retrorsine N-oxide and quercetin are being described for the first time in Senecio oleosus.
