The steam-distilled essential oils from plants of Artemisia afra (Jacq.) (Compositae) from the wild and organically cultivated at two pilot sites in Zimbabwe were analysed by GC±MS. The major components of plants in the wild were artemisia ketone (6.3±41.9%), 1,8-cineole (0.1±27.9%), a-copaene/camph

✦ Synopsis
The essential oil of aerial parts of Porophyllum ruderale (Jacq.) Cass. was analysed by HRGC, HRGC±MS (quadrupole) and 26 components (93% of the total composition) were identi®ed. The enantiomeric distribution of b-pinene, sabinene, 4-terpineol and a-terpineol was studied by multidimensional HRGC±HRGC. The major component was sabinene (64%) with an enantiomeric purity of 97% for ()-sabinene. Copyright
