Abstract:

Objective To investigate the repellent activities of essential oil from chestnut flower and its four active components as well as distillate against Aedes albopictus. Methods Component analysis of essential oil from chestnut flower was performed by gas chromatography-mass spectroscopy. The repellent activities of essential oil and its four active components as well as distillate against Ae. albopictus were determined using the effective protection time and repellent rate. Results Essential oil from chestnut flower mainly contained 11 compounds belonging to aldehydes, ketones, alcohols, and esters. The effective repellent times of essential oil and its individual active components (menthol, geraniol, linalool, and terpineol) were 3.00, 4.25, 6.00, 3.75, and 5.00 h, respectively. The effective repellent times of chestnut flower distillate and commercial toilet water were 0.08 and 2.25 h, respectively. These data were indicative of the strong repellent activity of essential oil from chestnut flower. The repellent activity of distillate was improved through an orthogonal experiment, with individual active components of essential oil as enhancers and 100 ml of distillate as a basic reagent. With the optimized formula, the protection time of distillate was extended to 2.50 h. Conclusion Essential oil from chestnut flower has strong repellent activity, which can be used as an active mosquito-repellent component to develop ethanol-free toilet water.

摘要:

目的 研究板栗花精油及精油4种单一有效组分、板栗花蒸馏液对蚊虫的驱避活性。方法 采用气质联用法(GC-MS)对板栗花精油进行成分分析;以白纹伊蚊为试虫,并以有效保护时间及驱避率测定精油及其4种单一有效组分和板栗花蒸馏液的驱避活性。结果 板栗花精油主要有醛、酮、醇、酯类化合物11种,精油及其单一有效组分薄荷醇、香叶醇、芳樟醇和松油醇的有效驱避时间分别为3.00、4.25、6.00、3.75、5.00 h,而板栗花蒸馏液仅为0.08 h,市售花露水为2.25 h,显示出板栗花精油具有显著的驱避活性。同时,以有效单一组分为强化剂,以100 ml板栗花蒸馏液为基础,通过正交实验,优化板栗花蒸馏液的驱蚊活性,得到板栗花花露水配方,其驱蚊有效时间为2.50 h。结论 板栗花精油具有驱避作用,可以开发以其为有效驱蚊组分的无醇花露水。
