Abstract

The Asteraceae (Compositae) family is one of the largest angiosperm families that has a large number of aromatic species. is a well-known medicinal plant that is used in the treatment of various diseases due to its essential oil (EO). The EO of both Saudi and Egyptian ecospecies were extracted via hydrodistillation, and the chemical compounds were identified by GC-MS analysis. The composition of the EOs of Saudi and Egyptian ecospecies, as well as other reported ecospecies, were chemometrically analyzed. Additionally, the phytotoxic activity of the extracted EOs was tested against the weeds and . In total, 80 compounds were identified from both ecospecies, of which 61 were Saudi ecospecies, with a preponderance of -pinene, isoshyobunone, 6-epi-shyobunol, -pinene, and -terpinolene. However, the Egyptian ecospecies attained a lower number (34 compounds), with spathulenol, hexahydrofarnesyl acetone, -bisabolol, and τ--cadinol as the main compounds. The chemometric analysis revealed that the studied ecospecies and other reported species were different in their composition. This variation could be attributed to the difference in the environmental and climatic conditions. The EO of the Egyptian ecospecies showed more phytotoxic activity against and than the Saudi ecospecies. This variation might be ascribed to the difference in their major constituents. Therefore, further study is recommended for the characterization of authentic materials of these compounds as allelochemicals against various weeds, either singular or in combination.

摘要

菊科是最大的被子植物科之一，有大量芳香物种。是一种著名的药用植物，因其精油（EO）可用于治疗各种疾病。沙特和埃及生态物种的精油均通过水蒸馏法提取，并通过气相色谱-质谱联用（GC-MS）分析鉴定化学成分。对沙特和埃及生态物种以及其他已报道生态物种的精油成分进行了化学计量学分析。此外，还测试了提取的精油对杂草和的植物毒性活性。从这两个生态物种中共鉴定出80种化合物，其中沙特生态物种有61种，以α-蒎烯、异丁香酮、6-表丁香醇、β-蒎烯和γ-萜品烯为主。然而，埃及生态物种的化合物数量较少（34种），主要化合物为匙叶桉油烯醇、六氢法尼基丙酮、β-红没药醇和τ-杜松醇。化学计量学分析表明，所研究的生态物种和其他已报道物种在成分上存在差异。这种差异可能归因于环境和气候条件的不同。埃及生态物种的精油对和的植物毒性活性比沙特生态物种更强。这种差异可能归因于它们主要成分的不同。因此，建议进一步研究这些化合物作为针对各种杂草的化感物质的真实材料的特性，无论是单一还是组合使用。
