title: The essential oil of Origanum vulgare L. ssp. vulgare growing wild in vilnius district (Lithuania).
abstract: The plants of wild Origanum vulgare L. ssp. vulgare were collected in 10 localities of Vilnius district (Lithuania) in 1995-1999. The main constituents of the essential oils from 8 localities were beta-ocimene (14.9-21.6%), germacrene D (10.0-16.2), beta-caryophyllene (10.8- 15.7%) and sabinene (6.6- 4.2%). The essential oils from two localities contained only three above compounds as major components: germacrene D, beta-ocimene and sabinene or beta-caryophyllene, beta-ocimene and germacrene D. Three chemotypes of essential oils were identified. The main chemotype was beta-ocimene germacrene D-beta-caryophyllene. The terpenic hydrocarbons made up 52.8-80.6% of the essential oils. The 42 identified components made up 85.6-98.0% of the essential oil.
