The alpha-terpenyl acetate chemotype of essential oil of Thymus pulegioides L

The composition of the essential oils of Thymus pulegioides L. plants growing wild in Vilnius district (Lithuania) with "ester", lemon and carvacrol (phenol) odours were collected in one location and investigated by GC, GC/MS and IR-spectroscopy. The essential oils with lemon and carvacrol odour belong to corresponding known citral-geraniol and carvacrol chemotypes. The essential oil of plants with "ester" odour containing 50-70% of alpha-terpenyl acetate belong to alpha-terpenyl acetate chemotype, which was not noticed earlier in Thymus pulegioides L. species.
