| چکیده مقاله |
| The present study aimed to investigate and compare the phytochemical profiles of terpenoids, specifically monoterpenes and sesquiterpenes, in two distinct ecotypes of Tanacetum parthenium. using Gas Chromatography-Mass Spectrometry (GC-MS). The objective was to quantify the differential accumulation of these secondary metabolites, which are crucial for the plant's ecological interactions and potential pharmacological properties [1]. Essential oils were extracted from aerial parts of each ecotype via hydrodistillation and subsequently analyzed by GC-MS [2]. Compound identification was based on retention indices and mass spectral matching with reference libraries [3]. Quantitative data revealed significant inter-ecotype variation. KC ecotype was characterized by a dominant presence of a specific sesquiterpene (5-epi-Neointermedeol, 7.51%) and a monoterpene (trans-Verbenyl acetate, 7.89%). In contrast, the KD ecotype exhibited higher abundance of a different sesquiterpene (7-epi-Amiteol, 7.51%) and monoterpenes such as Camphene (13.04%) and p-Cymene (2.71%). Several compounds were exclusive to one ecotype; for instance, (-)-Bornyl acetate (a monoterpene) was detected only in the KD ecotype, while β-Eudesmol (a sesquiterpene) was found solely in the KC ecotype. The overall compositional disparity indicates a pronounced chemotypic variation within T. parthenium. These results suggest that genetic and/or environmental factors significantly influence terpenoid biosynthesis pathways in this species. The distinct phytochemical signatures not only contribute to the chemotaxonomic knowledge of the Tanacetum genus but also highlight the potential for selecting specific ecotypes as sources of particular terpenoid compounds for future bioprospecting efforts. |
