	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.},
