The Composition of Essential Oil from Three Ecotypes of Origanum Vulgare L. Ssp. Vulgare Cultivated in Poland
نویسندگان
چکیده
The chemical composition of oregano essential oil of different origin extracted from oregano plants grown in south-eastern Poland was analysed using the gas chromatography mass spectrometry (GC-MS) and gas chromatography flame ionization detector (GC-FID). The dominant compound was sabinene; its percentage proportion ranged from 10.85% to 25.46%, depending on the ecotype studied. Moreover, the oregano volatile oil was characterized by a significant percentage of the following compounds: germacrene D (9.36-15.34%), Z-(β)-ocimene (9.10-16.33%), and E-caryophyllene (9.3812.87%). The investigated oil did not contain phenolic compounds.
