| description | (1) Background: The essential oils (EOs) of <i>Sideritis</i> L. have attracted great interest due to their pharmacological activities and potential applications in the cosmetic and perfume industries. The aim of this work was to study the EO chemical composition of three of the most popular, in Greece, mountain tea species: namely, these include <i>Sideritis scardica</i>, <i>Sideritis raeseri</i>, and <i>Sideritis syriaca</i>. (2) Methods: The EOs were obtained from the aerial parts of three <i>Sideritis</i> species that were cultivated in various regions of Greece by hydrodistillation, and the chemical composition was studied by gas chromatography–mass spectrometry (GC-MS) analysis. (3) Results: The EOs of the <i>Sideritis</i> species—<i>S. scardica</i> (SSC1, SSC2, SSC3), <i>S. raeseri</i> (SR1, SR2, SR3), and <i>S. syriaca</i> (SS1, SS2, SS3)—were analyzed by GC-MS, and they showed both qualitatively and quantitatively high variation in their chemical composition. (4) Conclusions: The EOs of <i>S. scardica</i> and <i>S. raeseri</i> from three different regions of Greece, and the <i>S. syriaca</i> from three different localities of Crete Island in Southern Greece, showed high chemical variability. Although 165 different components were found to be present in the nine samples through GC-MS analysis, only 7 (1-octen-3-ol, linalool, <i>trans</i>-pinocarveol, <i>p</i>-mentha-1,5-dien-8-ol, <i>α</i>-terpineol, myrtenol, and verbenone) were common components in the nine EOs, which were identified to be highly variable in different percentages among the samples. Even the EOs of SS1 and SS2, which were cultivated nearby, showed different GC profiles. The composition variation observed might be attributed to differentiations in the soil and climatic conditions. |
