ResumoAbstract The essential oils isolated from the leaves of Ageratum houstonianum Mill, and Ageratum conyzoides L. by hydrodistillation were analysed by GLC and GC‐MS. The essential oil of A. houstonianum contained 7‐methoxy‐2,2‐dimethylchromene (precocene I) and ageratochromene (precocene II) in almost similar amounts (32% and 24% respectively) whereas that of A. conyzoides was rich in precocene I (81%) and poor in precocene II (0.2%). Our findings are compared with those of the literature.
