Tanacetols A and B,non-volatile sesquiterpene alcohols,from Tanacetum vulgare

Chemical investigation of a rare chemotype of Tanacetum vulgare attorded a series of non-volatile sesquiterpene alcohols which have been called tanacetols. The structures of tanacetols A and B, the two most abundant, have been established on the basis of spectroscopic data, chemical reactions and X-ray diffraction analysis of tanacetol A and tanacetol B acetate.
