Abstract

The essential oil and headspace obtained from odorous parts of Thymus moesiacus Velen., an endemic species from Bosnia and Herzegovina, were subjected to capillary GC/MS analysis. The identification of the volatile constituents was accomplished by computer library search, retention indices RI, and the visual interpretation of mass spectra with those found in the literature [1] and in the laboratory own database.

Fifty-seven compounds were identified in both samples: fifty-five in essential oil, and thirty-five in headspace sample, representing 99.27% and 99.49%, respectively. The most abundant components in essential oil were gamma-muurolene (24.68%), thymol (8.62%) and bornyl acetate (8.26%), while the main constituents of the headspace sample were p-cymene (18.07%), alpha-pinene (15.34%), and gamma-muurolene (12.91%).

Presented results significantly differ from those previously published [2,3], which is in agreement with the fact of complex chemical polymorphism of this genus.
