| Experiment Detail |
The aerial parts of samples from collective populations of T. carnosus were collected during the vegetative phase (February 2000), at the beginning of the flowering phase (May 2000) and during the flowering phase (July 2000) at Quinta do Lago (Algarve). AQLM: collected in May, beginning of flowering phase; AQLJ: collected in July, flowering stage; AQLF: collected in Feb, vegetative stage.

| Factor Function |
All the oil samples collected in Quinta do Lago (QL) were dominated by borneol (26-31%) and camphene (9-18%), but the third main component varied according to the harvesting period. Bornyl acetate was the third main component (9-13%) in the flower oil and in the aerial parts oils collected in May and July, whereas terpinen-4-ol (8%) was the third main component in oil collected in February from vegetative phase plant material. A fourth main component, alpha-pinene (4-9%), was also present in relative high amounts in the QL oils.
