The potential of utilizing Onopordum acanthium essential oil and its major constituents as environment friendly herbicides was investigated. In total 29, 25, and 18 compounds were identified from flower, leaf, and stem oils, representing 94.77%, 80.02%, and 90.74% of the total oil, respectively. Flower and stem oils were found to be rich in n-alkanes, which accounted for 57.33% in flower oil, and 82.33% in stem oil. Flower oil exerted potent inhibitory activity on both receiver species, Amaranthus retroflexus and Poa annua, which nearly completely suppressed seed germination at 5 mg/mL, and β-eudesmol is the most likely responsible compound for its phytotoxicity; in comparison, leaf and stem oils exhibited much weaker inhibitory activity on A. retroflexus, and stimulatory effect on P. annua when tested concentration was below 2.5 mg/mL. Alkanes in the oils were found to exert relatively weak plant growth regulatory activity. This report is the first on the chemical profile and phytotoxic action of O. acanthium oil as well as the phytotoxicity of β-eudesmol.
研究了刺果甘草精油及其主要成分作为环保型除草剂的潜力。从花、叶和茎油中共鉴定出 29、25 和 18 种化合物，分别占油总量的 94.77%、80.02%和 90.74%。花和茎油富含正烷烃，花油中占 57.33%，茎油中占 82.33%。花油对受体物种反枝苋和草地早熟禾均表现出很强的抑制活性，在 5mg/mL 时几乎完全抑制种子萌发，β-桉叶醇可能是其植物毒性的主要原因化合物；相比之下，叶和茎油对反枝苋的抑制活性较弱，在测试浓度低于 2.5mg/mL 时对草地早熟禾表现出刺激作用。油中的烷烃被发现具有相对较弱的植物生长调节活性。本报告首次报道了刺果甘草油的化学成分和植物毒性以及β-桉叶醇的植物毒性。
