摘要：

Biochemical and morphological components of 16 Pelargonium species and the P. xhortorum interspecific complex were examined. Inflorescences and leaves of each species were analyzed for anacardic acids and the presence of glandular trichomes. Three species of the section Ciconium, P. acetosum, P. frutetorum, and P. inquinans, produced anacardic acids in association with glandular trichomes. Only P. inquinans and P. frutetorum contained omega 5-anacardic acids. An evolutionary model for the origin of anacardic acids and omega 5-desaturation is proposed.
