“…In the previous study in Lithuania, the results showed that meteorological factors differently influenced the accumulation of compounds in Thymus sp. [18]. The differences found between our results and those of other authors can be attributed to the fact that essential oils are a heterogeneous group of mixtures that are affected by meteorological factors.…”

In order to increase the diversity of medicinal plants and biologically active compounds accumulated in them, considerable attention is given to introduction of Artemisia L. genus plants in Lithuania. The aim of our study was to determinate the qualitative and quantitative composition of essential oils of Artemisia pontica L. introduced in Lithuania. The object of investigation – Artemisiae pontici herba were prepared in the Scientific Sector of Medicinal and Aromatic Plants, Scientific Department of Botanical Garden at Vytautas Magnus University in 2018–2019. Essential oils were separated by hydrodistillation method, their composition was analysed by gas chromatography/mass spectrometry methods in the Faculty of Pharmacy at Lithuanian University of Health Sciences in 2018–2020. The obtained results showed that a statistically significant (p > 0.05) higher amount and diversity of compounds from Artemisiae pontici herba essential oils were assessed in 2018 when HTC = 1.32. A strong correlation (r = 0.740) was assessed between the average of active temperatures and precipitation in 2019. The content of compounds was by 33.3% lower when HTC = 0.91. The other major compounds were 1,8-cineole (46.86%), 1,4-cineole (37.92%) and camphor (29.41–33.02%).

“…1) obtained from essential oils of dictamnus (Origanum dictamnus), oregano (Origanum vulgare), and thyme (Thymus vulgaris): the oil contains 42.9-82.3%, 8.6-65.1%, and 2.2-81.5% of carvacrol, respectively [5,[16][17][18][19][20][21][22][23][24][25][26][27]. Other oils rich in carvacrol are obtained from marjoram (Origanum majorana), lemon thyme (Thymus pulegioides), and summer savory (Satureja hortensis); its content in oil is: 2.2-48.7%, 32.8-62.6%, and 34.4-50.6%, respectively [5,22,23,[28][29][30][31]. Oregano and thyme essential oils are used in dietary supplements, aromatherapy, and phytotherapy for the treatment of colds, and as active antifungal, insecticidal, and antibacterial agents [5,23,25,27,29].…”

The paper presents multivariate partial least-squares calibration model defined for the identification and simultaneous determination of phenolic terpenoids-eugenol, carvacrol, and thymol-by means of the differential pulse voltammetry. For the first time, using boron-doped diamond electrode signal, electrochemical distinction of carvacrol and thymol, despite the short distance between the peaks (15 mV), was described. The analytes' concentrations applied in the calibration model were selected using the 3-factorial central composite design. The multivariate partial least-squares model, with optimized data pre-processing, was used for determination of eugenol, carvacrol, and thymol in the concentration ranges of 0.77-13.86, 0.58-10.40, and 0.73-7.32 mg/dm 3 , respectively. The quality of the method, expressed by the root-mean-squared error of calibration was 0.55, 0.20, and 0.26 mg/dm 3 for the specified analytes. The recovery in the analysis of the pure signals was 98.92%, 101.62%, and 101.46%, what confirmed the possibility of clearly distinguishing the thymol and carvacrol peaks. In the spiked honey samples, the accuracy of eugenol, carvacrol, and thymol determination, expressed by the root-meansquared error of prediction, was in the range 0.20-0.83 mg/dm 3 , and recovery in the range 80.9-111.9%. Application of the presented model not only enables electrochemical identification and simultaneous determination of eugenol, carvacrol, and thymol, but also allows rapid, accurate, and low-cost verification of authenticity of the commercial products.

“…Results showed that geraniol was more common in the eastern and the central Lithuania with the more continental climate because there temperature in January is lower [ 23 ], the sum temperature in April–July higher (except Sūduva climatic sub-district) compared to other parts of Lithuania ( Table 6 ). Previous studies also showed the positive effect of temperature on geraniol percentage in Thymus pulegioides plants of geraniol chemotype [ 22 ]. Individuals of T. vulgaris geraniol chemotype were also more tolerant to low temperature and temperature fluctuation in winter [ 42 , 43 , 44 , 45 ].…”

“…Same environmental factors can unequally effect on different volatile compounds. For example, cultivation of phenolic and non-phenolic chemotypes of large thyme in some locality showed that higher temperature in April–July stimulates essential oil and geraniol accumulation, meanwhile higher photosynthetically active solar radiation inhibites geraniol accumulation in plants of geraniol chemotype, photosynthetically active solar radiation stimulates and higher temperature inhibites essential oil accumulation in plants of carvacrol chemotype, higher temperature in April–July stimulates essential oil accumulated in linalool chemotype of T. pulegioides [ 22 ]. Therefore, very likely that same environmental factors could impact different effect on distribution of different chemotypes in space.…”

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.
