Lignans from the plant species Achillea lingulata

Abstract

Five lignans with a 2,6-diaryl-3,7-dioxabicycloŠ3.3.0Ćoctane skeleton epieudesmin, kobusin, pinoresinol, fargesin and sesartemin, were isolated from the aerial parts and roots of Achillea lingulata. Their structures were identified by comparison of their 1H-NMR and MS data to those in the literature. Fargesin and pinoresinol have not been isolated previously from any species of the genus Achillea.
