薄荷叶的精油 (EO) 是通过加氢蒸馏法提取的。GC-MS和GC-FID分别测定了21种化学成分，占油品总量的97.5%。主要化学成分包括薄荷醇（41.6%）、L-薄荷酮（24.7%）、异薄荷醇（6.3%）和柠檬烯（5.0%）。通过熏蒸、接触和驱虫活性生物测定法评估了所得 EO 及其两种主要成分对黑栗赤霉、 Lasioderma serricorne 和 Liposcelis bostrychophila 成虫的生物活性。EO 对栗木具有显着的熏蒸和接触毒性（ LC ₅₀ = 18.1 mg/L 空气和 LD ₅₀= 2.9 μg/成人，分别）、 L. serricorne （LC ₅₀ = 68.4 mg/L 空气和 LD ₅₀ = 12.6 μg/成人，分别）和 L. bostrychophila （LC ₅₀ = 0.6 mg/L 空气和 LD ₅₀ = 49.8 μg/成人，分别）成人。同时，在最高测试浓度下，EO 对 T. castaneum 和 L. serricorne 成虫的驱避效果与阳性对照相当。薄荷醇和 L-薄荷酮是总油中的两个主要成分。其中，L-薄荷酮对目标昆虫具有显着的杀虫活性，薄荷醇具有显着的驱避作用。结果表明，EO M. piperita 叶子和两种经过测试的成分有可能被开发为天然杀虫剂和驱虫剂，用于控制储存的害虫。

Toxicity and repellent activity of essential oil from Mentha piperita Linn. leaves and its major monoterpenoids against three stored product insects

The essential oil (EO) from leaves of Mentha piperita was extracted by hydrodistillation. Twenty-one chemical components, accounting for 97.5% of the total oil, were determined by GC-MS and GC-FID. The major chemical components included menthol (41.6%), L-menthone (24.7%), isomenthol (6.3%), and limonene (5.0%). The bioactivity of the obtained EO and its two major components against Tribolium castaneum , Lasioderma serricorne , and Liposcelis bostrychophila adults were evaluated by fumigation, contact, and repellent activity bioassay. The EO showed significant fumigation and contact toxicity against T. castaneum (LC₅₀ = 18.1 mg/L air and LD₅₀ = 2.9 μg/adult, respectively), L. serricorne (LC₅₀ = 68.4 mg/L air and LD₅₀ = 12.6 μg/adult, respectively), and L. bostrychophila (LC₅₀ = 0.6 mg/L air and LD₅₀ = 49.8 μg/adult, respectively) adults. Meanwhile, the repellent effect of the EO on T. castaneum and L. serricorne adults was comparable to that of the positive control at the highest tested concentration. Menthol and L-menthone were two major components in total oil. Among them, L-menthone exhibited significant insecticidal activity on target insects, and menthol showed notable repellent effects. The results indicated that the EO of M. piperita leaves and two tested components have potential to be developed as natural insecticides and repellents for the control of stored product insect pests.
