This study aims to determine the chemical composition of essential oil (EO) extracted from the aerial parts of L., as well as its phytotoxicity on germination and seedling growth against some invasive weed species of cereal crops and wheat (, cultivar Chen'S). Gas chromatography/mass spectrometry (GC-MS) identified 51 components (representing 95.26% of the total EO composition). Shyobunone (10.14%), 1-phellandrene (9.63%), α-cadinol (7.46%), δ-cadinene (7.45%), and germacrene D (7.09%) were the most abundant compounds. The effect of EO on weed species germination, root and shoot growth was moderate to strong. When 0.02% and 0.03% of the oil were applied, EO had a strong phytotoxic effect, resulting in 100% failure of germination. In addition to determining the responsible compound, the observed phytotoxicity suggestedthat essential oil could be used as an environmentally friendly biopesticide.
本研究旨在确定从L.地上部分提取的精油（EO）的化学成分，以及其对一些谷类作物和小麦（品种陈'S）的入侵杂草种子萌发和幼苗生长的植物毒性。气相色谱/质谱联用仪（GC-MS）鉴定出51种成分（占精油总成分的95.26%）。异菖蒲酮（10.14%）、1-水芹烯（9.63%）、α-杜松醇（7.46%）、δ-杜松烯（7.45%）和吉马烯D（7.09%）是含量最高的化合物。精油对杂草种子萌发、根和芽生长的影响为中度至重度。当施用0.02%和0.03%的精油时，精油具有很强的植物毒性，导致100%的种子萌发失败。除了确定起作用的化合物外，观察到的植物毒性表明，精油可作为一种环保型生物农药。
