Abstract:

Two samples of wild thyme (Thymus serpyllum L.), which were collected from different locations in Hungary, were subjected to CO2 extraction and oil isolation by hydrodistillation. Using GC and GC/MS as the method of analysis their compositions were compared. Analysis revealed that the oils and extracts contained the same components although they differed quantitatively. The concentration of p-cymene, borneol, nerol and carvacrol was higher in the distilled oil than in the volatile concentrate obtained by SFE.
