	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.},

	abstract = {Supercritical fluid extraction (SFE) with carbon dioxide and hydrodistillation (HD) were compared as methods to isolate essential oil from thyme herb (Thymus serpyllum, L.). The SFE extraction was performed in a semibatch apparatus and the rate of extraction was found dependent on the extraction pressure and temperature and on the amount of carbon dioxide passed through the extractor. The most suitable conditions for the extraction were 11 MPa and 50{\textdegree}C. The compounds extracted by both SFE and HD were identified by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The difference in the aroma of the products was quite noticeable and can be attributed to qualitative and quantitative differences in the extracts and hydrodistillates. Predominance of aromatic alcohols carvacrol and thymol and their biosynthetic precursors p-cymene and γ-terpinene was revealed in both SFE extracts and HD oil. The SFE extracts also contained water and cuticular waxes; longer extraction times and higher pressures resulted in a higher percentage of water and waxes in the extract.},
