Sesquiterpene Lactones from Achillea fragrantissima

Abstract

In continuation of our chemical investigation on some medicinal plants of the genus Achillea, chromatographic investigation of the methylene chloride/methanol (1:1) extract of the air-dried aerial parts of Achillea fragrantissima (family Asteraceae) afforded seven sesquiterpene compounds (1-7). Herein, we report the carbon data for the metabolites 1, 2, 6 and 7 for the first time. Also, revise the structure of the published compound 2. Structures were elucidated by 1D and 2D spectroscopic analyses.
