Abstract

The essential oil isolated from the leaves and flowers of Ageratum conyzoides L. were analysed by GC and GC–MS. The oil contained ageratochromene (precocene II, 25.89%); the sesquiterpene β‐caryophyllene (23.79%); demethoxyageratochromene (precocene I, 14.76%) and some monoterpene hydrocarbons, with percentages of 2–5.5%. Comparative analysis with data from Cameroon, Ghana and Vietnam is also reported. Copyright Β© 2003 John Wiley & Sons, Ltd.
