Abstract

The essential oils of Origanum vulgare L. ssp. hirtum (Link) letswaart and Origanum vulgare L ssp. vulgare (Fam. Lamiaceae), cultivated in Hungary, have been studied by GC and GC-MS and the qualitative and quantitative chemical composition of the essential oils in the two species have been compared. O. vulgare ssp. hirtum oil was found to contain carvacrol (76.4%), γ-terpinene (6.6%), thymol (0.23%), and p-cymene (4.7%) as the main constituents whereas the major compounds in O. vulgare ssp. vulgare oil were p-cymene (22.3%), coryophyllene oxide (10.2%), sabinene (7.9%), γ-terpinene (5.1%), thymol (0.34%), and spathulenol (4.8%). The stability of content and composition of the oils during the flowering period (economically beneficial period) were observed. The effect of long-term storage on the composition of the oil was also investigated for both the crude and distilled oil of Origanum vulgare ssp. vulgare.
