Structures of phenolic compounds isolated from Eupatorium adenophorum

Abstract

 Nowadays, phytochemical profiles of plants are the basis for the evaluation of their biological activities and ecological impact on environment and other living species. Chromatographic separation and NMR structural analysis were used in this paper to study the occurrence of six phenolic compounds in water fraction from the leaves of Eupatorium adenophorum Spreng. Structures of the compounds were identified as 4-hydroxybenzoic acid, methyl 3,4-dihydroxybenzoate, isovanillic acid, 5-O-glucopyranosylthymoquinol, 2-O-b-D-glucopyranosylcinnamic acid, and quercetagetin 7-O-b-D-glucopyranoside.
