The aim of this research was to evaluate larvicidal activity of the essential oil of Allium tuberosum Rottler ex Sprengle roots and its constituents against larval mosquitoes (Aedes albopictus Skuse). Essential oil of A. tuberosum was obtained by hydrodistillation and analyzed by gas chromatography and gas chromatography-mass spectrometry. The major constituents of the oil were found to be sulfur-containing compounds, including allyl methyl trisulfide (35.19%), diallyl disulfide (28.31%), diallyl trisulfide (20.91%), and dimethyl trisulfide (12.33%). The essential oil of A. tuberosum exhibited larvicidal activity against the fourth-instar larvae of Ae. albopictus, with an LC50 value of 18 μg/ml. The constituents compounds-diallyl trisulfide (LC50 = 4 μg/ml) and diallyl disulfide (LC50 = 6 μg/ml)-possessed stronger larvicidal activity than allyl methyl trisulfide (LC50 = 27 μg/ml) and dimethyl trisulfide (LC50 = 35 μg/ml) against the fourth-instar larvae of Ae. albopictus. The results indicated that the essential oil of A. tuberosum and its major constituents have good potential as a source for natural larvicides.
本研究的目的是评估韭菜根精油及其成分对蚊幼虫（白纹伊蚊）的杀幼虫活性。通过水蒸馏法获得韭菜精油，并采用气相色谱和气相色谱 - 质谱联用仪进行分析。该精油的主要成分是含硫化合物，包括烯丙基甲基三硫化物（35.19%）、二烯丙基二硫化物（28.31%）、二烯丙基三硫化物（20.91%）和二甲基三硫化物（12.33%）。韭菜精油对白纹伊蚊四龄幼虫表现出杀幼虫活性，LC50值为18μg/ml。成分二烯丙基三硫化物（LC50 = 4μg/ml）和二烯丙基二硫化物（LC50 = 6μg/ml）对白纹伊蚊四龄幼虫的杀幼虫活性比烯丙基甲基三硫化物（LC50 = 27μg/ml）和二甲基三硫化物（LC50 = 35μg/ml）更强。结果表明，韭菜精油及其主要成分作为天然杀幼虫剂来源具有良好潜力。
