- Chemical Constituents of Eupatorium erythropappum : Eupathronoside - A New Flavanone Glucoside and (-)-1S,2R,4S,5R-2,5-Dihydroxy-p-menthane - A New Monoterpene Diol
-
A new flavanone glucoside designated as eupathronoside (1) and a new monoterpene diol shown to be (-)-1S,2R,4S,5R-2,5-dihydroxy-p-menthane (3) have been isolated from the whole plant of Eupatorium erythropappum Robinson along with kaempferyl 5-methyl ether (4), (+)-3S,4S,6R-3,6-dihyroxy-p-menth-1-ene (5), physcon (6), coumarin, methyl p-coumarate and β-sitosterol.Eupathronoside has the structure as 3,4'-dihydroxy-7-methoxyflavanone-5-O-β-D-glucoside (=7-O-methyl-aromadendrin-5β-D-glucoside).
