GRAPHICAL ABSTRACT


ABSTRACT


 Phytochemical investigation of the aerial parts of Senecio desfontainei afforded one new benzoxepin derivative, Senecioside (1) along with eleven known compounds (2-12). Their structures were assigned from 1H and 13C NMR spectra, DEPT and by 2D COSY, NOE, HSQC and HMBC experiments. All these compounds were tested for antioxidant activity in the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay. Among them, compounds 2, 3, 4, 6 and 9 showed significant antioxidant activity against DPPH radicals.
