The chemical profile and phytotoxic activity of the essential oil extracted from was investigated. In total 17 compounds were identified by GC/MS, representing 99.17% of the entire oil, among which α-thujone (64.46%) and eucalyptol (10.15%) were the most abundant constituents. The major components, their mixture as well as the essential oil exhibited significant phytotoxic activity against , , and , with their IC values ranged from 1.55 ∼ 6.21 mg/mL (α-thujone), 1.42 ∼ 17.81 mg/mL (eucalyptol), 0.23 ∼ 1.05 mg/mL (the mixture), and 1.89 ∼ 4.69 mg/mL (the essential oil) on the four tested species. The mixture of the major constituents exerted more potent effect compared with each individual compound, indicating the possible involvement of synergistic effect of these two compounds.
对 中提取的精油的化学组成和植物毒性活性进行了研究。通过 GC/MS 共鉴定出 17 种化合物，占整个油的 99.17%，其中α-侧柏酮（64.46%）和桉油醇（10.15%）是最丰富的成分。主要成分、它们的混合物以及精油对 、 、 、 和 表现出显著的植物毒性活性，其 IC 值范围为 1.556.21 mg/mL（α-侧柏酮）、1.4217.81 mg/mL（桉油醇）、0.231.05 mg/mL（混合物）和 1.894.69 mg/mL（精油），在四种测试物种上。主要成分的混合物比每种单个化合物表现出更强的效果，表明这两种化合物可能存在协同作用。
