A study on Thymus vulgaris L. from Valencia (Spain)}, journal={Natural Volatiles and Essential Oils}, volume={7}, pages={29–50}, year={2020}, author={Llorens-molina, Juan Antonio and Vacas, Sandra and Burgals, Enrique and Santamarina, Mª Pilar and Verdeguer, Mercedes}, keywords={T.Vulgaris, Thin Layer Chromatography, Chemodiversity, Atypical individuals, Wild populations}, abstract={Chemodiversity of wild populations of aromatic plants is a valuable source of essential oils, whose composition may be suitable for <br />specific purposes according their biological activity. Furthermore, knowing the intrapopulational variability based on individual <br />analysis has allowed characterizing atypical profiles, which can reach high levels of active compounds. Obviously, it requires the <br />treatment of a high number of individual samples. In this work, a methodology to characterize T. vulgaris profiles in an area of <br />recognized biodiversity was proposed and applied. After Thin Layer Chromatography (TLC) screening data of 85 individual samples, <br />7 groups, and 13 individuals were classified. Then, 20 samples were subjected to GC/MS and GC/FID analysis, respectively. These <br />data were subjected to Hierarchical Agglomerative, Discriminant Analysis and ANOVA, which finally highlighted five profiles: (1) based <br />on the camphane skeleton (camphene, camphor and borneol), (2) rich in the oxygenated sesquiterpenic fraction, (3) rich in 1,8- <br />cineole, with appreciable amounts of camphor and borneol (typical chemotype from Eastern Iberian Peninsula), (4) camphor and <br />terpinen-4-ol as major compounds, and (5) linalool chemotype. It should be noted that the percentages of the main compounds in <br />these groups were higher than some of those described in the literature for similar chemotypes. In summary, the preliminary <br />screening by TLC, grouping individuals with similar profiles, allowed establishing a quick first approximation to the chemodiversity of <br />T. vulgarisin the studied area. Furthermore, the analysis of unclassified and potentially atypical individuals has also provided valuable <br />information to establish the final profiles. }, number={3}, publisher={Badebio Biotechnology Ltd.}
