“…Studies demonstrated that all territory of Lithuania is suitable for T. pulegioides , and the amount of essential oil in habitats of T. pulegioides varied from 0.20% to 1.32%. Literature data suggest that amount of essential oils of T. pulegioides growing in other European countries also can vary in the wide ranges: in Romania amount of essential oil varied from 0.7% to 1.1% [ 27 ], in Croatia—from 0.6% to 1.31% [ 11 ], in Portugal—1.8%, [ 28 ], in Kosovo—1.58% [ 29 ]. The analysis showed that higher amount of humus in soil positively, higher amounts of manganese and cobalt—negatively influenced the amount of essential oil in raw material collected in habitats of T. pulegioides ( Table 2 , Table 3 , Table 4 and Table 5 ).…”

Intraspecific chemical polymorphism is characteristic of essential oil bearing Thymus pulegioides (Lamiaceae). Soil chemical composition and climatic conditions can influence not only quantitative and qualitative composition of essential oils, but also on prevalence of different chemotypes in space. The purpose of study was to determine the impact of edaphic and climatic factors on T. pulegioides essential oil composition and potential chemotypes prevalence. It were investigated 131 habitats of T. pulegioides in all ten climatic sub-districts of Lithuania. Essential oils were isolated by hydrodistillation and analysed by GC-FID and GC-MS. The content of humus was estimated by oxidation method, the content of mobile potassium (K2O) and mobile phosphorus (P2O5)—flame photometry using 0.2 M HCl solution, the soil pH—electrometrically and 15 elements of soil—by energy-dispersive X-ray fluorescence. The meteorological data (temperature, rainfall, photosynthetically active solar radiation and sunshine duration) were obtained from the meteorological bulletins. Results showed that humus in soil positively, manganese and cobalt—negatively influenced on the essential oil accumulation in T. pulegioides. Carvacrol was the most common compound in the essential oil of T. pulegioides; higher amounts of sulphur and mobile phosphorus, lower amounts of sodium in soil, higher rainfall in blooming period are favourable for this compound and for potential prevalence of carvacrol chemotype. Geraniol was frequent in the eastern and the central part of Lithuania, where the temperature in vegetation season is higher, and in soils characterised by higher and lower amounts of sodium and chlorine, respectively. Thymol, linalool and α-terpinyl acetate were rare. Edaphic and climatic conditions can differently influence on essential oil yield and chemical composition of species as well as on potential prevalence of different chemotypes of same species in space.

Essential Oil Composition of Ten Species from Sect. Serpyllum of Genus Thymus Growing in Bulgaria

GC-MS/FID analysis of the essential oils of 10 Thymus species, belonging to Sect. Serpyllum, led to identification of 118 compounds accounting for 97.79–99.69% of the total oil. Thymus moesiacus, T. jankae, T. vandasii, T. longicaulis and T. sibthorpii were characterized by the presence of linalool (19.37–35.21%) as the major or dominant component, but differed significantly in the content of the other prominent components: linalyl acetate, geraniol, geranyl acetate, α-terpinyl acetate, myrcen-8-yl acetate, myrcen-8-ol, etc. α-Terpinyl acetate (66.79%), thymol (63.96%), carvacrol (42.65%) and germacrene D (42.15%) were the principal components of T. pulegioides, T. glabrescens, T. callieri and T. pannonicus, respectively. β-Myrcene (16.53%), cis-sabinene hydrate (13.58%), τ-cadinol (13.24%) and elemol (11.29%) determined the oil from T. thracicus as a mixed mono-/sesquiterpene chemotype. The obtained results revealed the existence of new chemotypes of T. moesiacus, T. thracicus, T. sibthorpii and T. longicaulis. The essential oil content of T. callieri and endemic T. vandasii is reported for the first time. The variations in the essential oils of different Thymus species from Sect. Serpyllum were examined by principal component analysis (PCA) and cluster analysis (CA).
