✦ Synopsis

The steam-distilled leaf and ¯ower oils of Ocimum basilicum L., Ocimum canum Sims and Ocimum gratissimum L., collected from 14 dierent locations in Togo, have been studied. Capillary gas±liquid chromatography and capillary gas-chromatography coupled with mass spectrometry were used to determine the percentage composition of these essential oils. The oils from O. basilicum mainly contained either estragole or a linalol±estragole mixture. In those from Ocimum canum, terpin-4-ol, linalol, U-terpinene and the sesquiterpene hydrocarbons (b-caryophyllene, (E)-a-bergamotene and bicyclogermacrene) were the major compounds. Thymol, U-terpinene and p-cymene were identi®ed as the most abundant constituents in the Ocimum gratissimum oils.
