	abstract = {The volatile oil compositions of Thymus pannonicus All. from nineteen different localities of Hungary were analyzed by GC/MS. The essential oil content of the Hungarian thyme samples varied between very low (0.14 mL/100 g DW) and fairly high (1.9 mL/100 g DW) values. Significant essential oil polymorphism was found: altogether twelve chemovarieties may have been determined, representing a way of adaptation to different habitat conditions. The main volatile compound of chemotype 1 was thymol (24.6-67.5\%), while in the case of chemotype 2, thymol (36.5-63.7\%) and p-cymene (11.5-27.3\%) predominated. Thymol (28.4-63.7\%), p-cymene (11.5-31.8\%) and γ-terpinene (9.7-20.9\%) were identified as the chief monoterpenes of chemotype 3, while chemotype 4 contained thymol (36.5\%), p-cymene (27.3\%) and neral (11.2\%). Chemotype 5 accumulated thymol (38.5\%), p-cymene (20.6\%), γ-terpinene (12.0\%) and β-bisabolene (10.3\%) as its main volatiles. The oil of chemotype 6 can be characterized by thymol (41.9\%), p-cymene (20.2\%), isoborneol (10.3\%) and {\~a}-terpinene (9.9\%), while that of chemotype 7 consisted of thymol (27.7\%), linalyl acetate (18.8\%), γ-terpinene (18.6\%) and α-cubebene (13.9\%). In the oil of chemotype 8, p-cymene (45.0\%), geraniol (13.6\%) and linalyl acetate (9.9\%) were found in higher percentages, while chemotype 9 mainly produced linalyl acetate (36.2\%) and geranyl acetate (20.2\%). Chemotype 10 accumulated germacrene-D (43.4) and β-caryophyllene (15.0\%), while the oil of chemotype 11 contained caryophyllene oxide (45.2\%), α-cubebene (15.7\%) and linalool (13.8\%) in high proportions. Germacrene-D (29.7\%), β-caryophyllene (22.0\%) and farnesol (10.4\%) were identified as main essential oil compounds of chemotype 12. The last nine chemotypes were new for the literature, while the first seven contained thymol as their chief compound. The role of certain sesquiterpenes was found to be considerable.},

	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.},
