Abstract:
This present study aims to characterize the essential oil compositions of the aerial parts of M. spicata L. and endemic M. longifolia ssp. cyprica (Heinr. Braun) Harley by using GC-FID and GC/MS analyses simultaneously. In addition, it aims to perform multivariate statistical analysis by comparing with the existing literature, emphasizing the literature published within the last two decades, conducted on both species growing within the Mediterranean Basin. The major essential oil components of M. spicata were determined as carvone (67.8%) and limonene (10.6%), while the major compounds of M. longifolia ssp. cyprica essential oil were pulegone (64.8%) and 1,8-cineole (10.0%). As a result of statistical analysis, three clades were determined for M. spicata: a carvone-rich chemotype, a carvone/trans-carveol chemotype, and a pulegone/menthone chemotype, with the present study result belonging to the carvone-rich chemotype. Carvone was a primary determinant of chemotype, along with menthone, pulegone, and trans-carveol. In M. longifolia, the primary determinants of chemotype were identified as pulegone and menthone, with three chemotype clades being pulegone-rich, combined menthone/pulegone, and combined menthone/pulegone with caryophyllene enrichment. The primary determinants of chemotype were menthone, pulegone, and caryophyllene. The present study result belongs to pulegone-rich chemotype.
摘要:
本研究旨在表征M.spicataL.和地方性M.lengifoliassp的地上部分的精油成分。赛普里卡(海因.Braun)Harley同时使用GC-FID和GC/MS进行分析。此外,它旨在通过与现有文献的比较来进行多元统计分析,强调过去二十年内出版的文献,在地中海盆地内生长的两个物种上进行。M.spicata的主要精油成分被确定为香芹酮(67.8%)和柠檬烯(10.6%),而M.longifoliassp的主要化合物。大蓝精油为pulegone(64.8%)和1,8-桉树脑(10.0%)。作为统计分析的结果,为M.spicata确定了三个分支:一种富含香芹酮的化学型,香芹酮/反式香芹醇化学型,和pulegone/menthone化学型,本研究结果属于富含香芹酮的化学型。Carvone是化学型的主要决定因素,和薄荷酮一起,pulegone,和trans-carveol。在龙叶分枝杆菌,化学型的主要决定因素被确定为pulegone和薄荷酮,有三个化学型进化枝富含普莱哥人,结合薄荷酮/pulegone,并结合薄荷酮/pulegone与石竹烯富集。化学型的主要决定因素是薄荷酮,pulegone,和石竹烯.本研究结果属于富含普乐酮的化学型。
