In addition to known eudesmanolide and germacranolide sesquiterpene lactones a new eudesmanolide, 1beta,4alpha,6alpha-trihydroxyeudesm-11-en-8alpha,12-olide was isolated from the aerial parts of Tanacetum densum subsp. amani. The structure of the new compound was established by spectral data; it showed weak antimicrobial activity.
