The essential oils of Anthospermum emirnense Baker and Anthospermum perrieri Homolle ex Puff , obtained by hydrodistillation in 0.03 and 0.02% yield, respectively, were analyzed by GC/MS. In both cases, the major constituents consisted of sesquiterpene hydrocarbons and oxygenated sesquiterpenes. The two species showed an important qualitative similarity, with 40 compounds common to A. emirnense and A. perrieri , including β ‐elemene, trans‐β ‐caryophyllene, caryophyllene oxide, and τ ‐cadinol, which were major components in both cases. When tested for antimicrobial activity, both essential oils showed similar profiles and exhibited interesting minimal‐inhibitory‐concentration ( MIC ) values towards Bacillus subtilis, Chryseobacterium indologenes, Flavimonas oryzihabitans , and Yersinia enterocolitica.
