摘要

Thymus pulegioides is widely distributed in Europe. It is an upright growing Thymus species that is characterised by a great variability in essential oil components. Up to now, six chemotypes have been described: thymol, carvacrol, geraniol, linalool, fenchone and alpha-terpenyl acetate. In Italy, only one wild population in Campania was analysed and described as thymol chemotype. In our research, three populations of T. pulegioides collected in Monti Pisani (Santagallo, Tuscany, 650 m a.s.l.) were analysed with respect to their essential oil amount and composition. The GC-MS analysis provided the separation and identification of approximately 34 components accounting for more than 98% of the composition of the hydrodistilled essential oils. Two populations were taken in the thymol chemotype group (containing 36.88 and 37.66% thymol), with the essential oil amounts of 1.53 g/100 g DW and 0.74 g/100 g DW. The third population, having typical lemon smell, contained higher amounts of geraniol as main compound (35.64%) with an essential oil level of 1.05 g/100 g DW.
