The chemical composition of the essential oils obtained by hydrodistillation from leaves of three samples of Chenopodium ambrosioides L. (Chenopodiaceae) growing in Benin were analyzed by GC and GC/MS. To date the biological functions of Chenopodium ambrosioides L. essential oils have not been demonstrated scientifically. We investigated the chemical composition of Chenopodium ambrosioides L. essential oils and their antiradical antimicrobial and anti-inflammatory activities. Twenty three compounds were identified and quantified in the oils. The essential oils are rich in hydrocarbons monoterpenic. The major compounds being ?-terpinene (48.8%, 60.0%, 63.7%), ascaridole (19.7%, 13.8%, 11.7%), p-cymene (19.1%, 15.4%, 19.0%) and isoascaridole (2.5%, 1.6%, 0.7%). The antiradical and anti-inflammatory.
