Abstract
A phytochemical investigation of the aerial parts of Eupatorium coelestinum led to the isolation of an amorphane sesquiterpene and a benzofuran glucoside. By means of spectroscopic methods, their structures were determined as 5 alpha,8 alpha-epoxy-4 alpha,6 beta-dihydroxyamorphan-2-one (1) and 2R*,3S*-toxol-7-O-beta-D-glucopyranoside (2). Compounds 1 significantly inhibited NF-kappa B activity in TNF-alpha-stimulated HeLa cells with the IC50 of 12.4 mu M. (C) 2011 Phytochemical Society of Europe. Published by Elsevier B.V.
