	abstract = {The seasonal variation in essential oil yield and composition from naturalized Thymus vulgaris L, in Central Otago, New Zealand, is reported. Essential oil yield (l/ha), from replicated, pilot-scale distillations, was influenced by both the held production of herb and the essential oil content of the herb. The oil yield peaked at 22.8 l/ha in December, after flowering had finished. Essential oil composition also varied significantly during the 13-month sampling period. Levels of the phenolic components, thymol and carvacrol, peaked at a total of 37\% after flowering in summer (December and January). p-Cymene was an important component of Central Otago thyme oils and ranged from 40\% to 50\% in winter and early spring (May to October), declining to 21\% in January. To maximize yields and phenol content of the oil, naturalized thyme in Central Otago should be harvested after flowering has finished in December.},

	abstract = {The aerial parts of Thymus lotocephalus were collected during the flowering and vegetative phases of the plant in the Algarve, Portugal. The oils were isolated by hydrodistillation and distillation-extraction and analysed by GC and GC-MS. The oil isolated from the flowers was obtained in a yield of 0.9\%, whereas those isolated from the leaves during flowering and vegetative phases showed lower yields, 0.7\% and 0.2\% (v/w), respectively. The oils isolated from both the flowers and the leaves were dominated by the oxygen-containing monoterpenes (57-64\%). The monoterpene hydrocarbons (11-22\%) and the oxygen-containing sesquiterpenes (7-14\%) were the two other main fractions of these oils. 1,8-Cineole (10-19\%), linalyl acetate (6-14\%) and linalol (4-12\%) were the main components of all the oils studied. Intermedeol (2-4\%), beta -caryophyllene oxide (2-3\%) and viridiflorol (1-3\%) were the main components of the oxygen-containing sesquiterpene fraction. The diterpene abietatriene was present in trace amounts (<0.05\%) in all the oils. Depending on the plant part studied and on the isolation procedure used, these oils can be characterized either by 1,8-cineole/linalol/linalyl acetate or 1,8-cineole type.
