本研究的目的是确定蒙古蒿挥发油的化学成分和杀虫驱避活性，并从挥发油中分离活性成分。提取A.采用水蒸气蒸馏法从蒙药中分离得到36个化合物，经GC-MS分析鉴定，主要成分为桉叶醇（39.88）、顺式马鞭草烯醇（14.93）、4-松油醇（7.20）、樟脑（6.02）和β-松油醇（4.20）。经进一步分离鉴定，从挥发油中分离得到5个化合物，分别为桉叶醇、马鞭草烯醇、4-松油醇、樟脑和β-松油醇。在测定过程中，发现L.银角草成虫对粗精油和分离成分的敏感性不同。4-松油醇对L.结果表明，其LD_（50）值为8.62 g/成虫。樟脑和β-松油醇的熏蒸活性较强（分别为3.27mg/L空气）。针对L.比粗精油和其他成分。此外，精油、桉叶醇、马鞭草烯醇和β-松油醇对L. serricorne成年人结果表明，挥发油及其分离的化合物有可能为食品和中药材保鲜中的昆虫防治提供更有效、更安全的天然杀虫剂或驱避剂。
The aims of this research were to determine the chemical composition and insecticidal and repellent activities of the Artemisia mongolica essential oil against Lasioderma serricorne and to isolate active constituents from the essential oil. The essential oil of A. mongolica was obtained by hydrodistillation and 36 components were identified with GC-MS. Eucalyptol (39.88%), (S)-cis-verbenol (14.93%), 4-terpineol (7.20%), (−)-camphor (6.02%), and α-terpineol (4.20%) were found to be major components. With a further isolation process, five constituents obtained from the essential oil were identified as eucalyptol, verbenol, 4-terpineol, camphor, and α-terpineol. In the progress of assay, it showed that L. serricorne adults had different sensitivities to the crude essential oil and isolated constituents. 4-Terpineol exhibited strongest contact activity against L. serricorne, showing the LD50 value of 8.62 μg/adult. Moreover, camphor and α-terpineol showed stronger fumigant activity ( and 3.27 mg/L air, resp.) against L. serricorne than crude essential oil and other constituents. In addition, the essential oil, eucalyptol, verbenol, and α-terpineol showed comparable repellency against L. serricorne adults. The results indicate that the essential oil and isolated compounds have potential to provide more efficient and safer natural insecticides or repellents for control of insects in food and Chinese medicinal materials preservation.
