✦ Synopsis

The composition of the essential oils isolated from different aerial parts of Argyranthemum pinnatijidum (L. fil.) Lowe ssp. pinnatijidum and of A. haemotomma (Lowe) Lowe was analysed by GC and GC-MS. The oils were isolated separately from the flowers, and from the leaves collected during the flowering period and the vegetative phase of the plants. The oil yields varied from ~0 . 0 5 % to 0.1% (v/w). The fraction of monoterpene hydrocarbons was dominant in all three oils isolated from each species, ranging from 49% to 69% in the oils of A. haemotomma, and from 43% to 71% in those of A. pinnatijidum. The main component of the oils was P-myrcene (28-50% and 39-62% of the oils isolated from A. haemotomma and A. pinnatifidum, respectively). Germacrene-D was the second most important component (10-18% of the oils from A. haemotomma and 10-23% of those from A. pinnatijidum) in all oils, except for the oil isolated during the vegetative phase of A. pinnutifidurn where bornyl acetate was the second main component (11Y0). The essential oils isolated from the two Argyranthemum species showed an overall qualitative similarity, and a quantitative resemblance with respect to their main components.
