“…With regard to our results, there is no significant correlation between content of flavonoids and origin of samples and therefore, more studies concerning not only a content of flavonoids, but also their structural identification should be done. Phytochemical analysis of other studies has revealed relationships among flavonoid profiles, morphology and locality (Horwath et al, 2008). Anthocyanins are phenolic compounds, which are responsible for the primary red and blue pigments in plants.…”

The content of phenolic compounds (total phenolic compounds, tannins, flavonoids and anthocyanidins) of three species of thyme (Thymus pulegioides, Thymus pannonicus, Thymus praecox) of different origin (Bohemian-Moravian highlands, Křivoklát and Považský Inovec) was determined using spectrophotometric methods of European Pharmacopoeia 8 th edition. Furthermore, the determination of the content of essential oil and analysis of its constituents was realised. The amount of total phenolics was determined by a spectrophotometric method using the Folin-Ciocalteu reagent. Their content ranged from 3.87 to 8.86%. The content of tannins was established on a preliminary determination of the total phenolics, followed by adsorption of tannins on hide powder. The amount of tannins in our samples varied from 1.96 to 5.65%. The content of total flavonoids was determined by a spectrophotometric method using aluminium chloride. Quantitative analysis of flavonoids has shown that content in our samples ranged from 0.59 to 1.52% expressed as luteolin-7-O-glucoside (λ = 392 nm) and from 0.41 to 1.12% expressed as rutin (λ = 420 nm). Anthocyanins represent a small amount of total polyphenol content in Thymus species. In our samples, the content of anthocyanins expressed as cyanidin-3-O-glucoside varied from 0.02 to 0.1%. The determination of essential oil was realised by method of European Pharmacopoeia 8 th edition. Its contents in our samples ranged from 0.2 to 0.75%. Gas chromatography-mass spectrometry was used for essential oil analysis. According to the presence of main monoterpene in Thymus essential oil, we can distinguish three chemotypes: thymol, carvacrol and linalool. Due to variations of chemical constituents of thyme essential oil, it was possible to observe a relationship between occurrence of certain chemotype and origin of sample. Differences in content of flavonoids have not shown a significant relationship to locality of origin.Predložená práca bola zameraná na stanovenie obsahu vybraných fenolových zlúčenín (celkové fenoly, triesloviny, flavonoidy a antokyány) troch rôznych druhov rodu Thymus (T. pulegioides, T. pannonicus, T. praecox) s rozdielnym pôvodom (Českomoravská vrchovina, Křivoklát a Považský Inovec). Na stanovenie týchto zložiek boli využité spektrofotometrické metódy Európskeho liekopisu, 8. vydanie. Zároveň bol stanovený aj obsah silice a bola vykonaná analýza jej zložiek. Obsah celkových polyfenolov bol stanovený spektrofotometrickou metódou s využitím Folin-Ciocalteovho činidla. Obsah kolísal od 3.87 % do 8,86 %. Obsah trieslovín bol realizovaný na základe predošlého stanovenia obsahu celkových fenolov, a to adsorpciou trieslovín na kožný prášok. Ich obsah sa pohyboval v rozmedzí 1,96 % do 5,65 %. Na stanovenie obsahu flavonoidov bola využitá spektrofotometrická metóda s chloridom hlinitým. Obsah flavonoidov vyjadrených ako luteolín-7-O-glukozid (λ = 392 nm) kolísal od 0,59 % do 1,52 % a obsah flavonoidov vyjadrených ako rutín (λ = 420 nm) sa pohyboval v rozmedzí od 0,41 % do 1,12 %.
