Abstract

MORALES, GLAUCO et al. CONSTITUENTS OF HELENIUM ATACAMENSE Cabr.. J. Chil. Chem. Soc. [online]. 2006, vol.51, n.1, pp.769-772. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072006000100002.

Constituents of Helenium atacamense Cabr were investigated following a preliminary screening of the biotoxicity against Artemia salina and the antitumoral activity of ethanol extract . Three compounds already identified were isolated from aerial parts of Helenium atacamense Cabr, and their structures were elucidated as helenalin, quercetin and 3-O-methylquercetin based on mass and various nuclear magnetic resonance techniques . Quercetin and 3- O- methylquercetin were tested by using TEAC Test

Keywords : Helenium atacamense Cabr; helenalin, quercetin and 3-O-methylquercetin; TEAC test.
