title: The main citral-geraniol and carvacrol chemotypes of the essential oil of thymus pulegioides L. growing wild in vilnius district (Lithuania).
abstract: Thymus pulegioides L. with lemon and carvacrol odor form the major part of plants growing wild in all 10 investigated localities during 1995-1997. The main components of the citral-geraniol chemotype of lemon-scented essential oil are the following (%): geraniol (14.9-30. 8), geranial (trans-citral, 9.7-19.7), beta-caryophylene (6.0-11.4), nerol (4.1-11.8), and neral (cis-citral, 0.1-9.5). The essential oil of carvacrol chemotypes contain more compounds that are characteristic of the thyme genus (%): carvacrol (16.0-22.2), beta-bisabolene (11.1-20.2), beta-caryophyllene (11.1-19.1), gamma-terpinene (5.8-16.2), p-cimene (5.5-10.4), thymol (3.3-9.8), and carvacrol methyl ether (5.6-8.6). The correlation between the odor and composition of the essential oil will help the users of wild thyme to choose the necessary chemotype for their purposes.
