Abstract

The use of larvicides, especially in endemic regions, is recommended for malaria control. However, due to the excessive use of synthetic larvicides, resistance in mosquitoes and environmental pollution have been challenges. In the current study, nanoliposome containing clove and cinnamon essential oils and their major ingredients, i.e., eugenol and cinnamaldehyde, were first prepared; particle size and successful loading were investigated using DLS (Dynamic Light Scattering) and ATR-FTIR (Attenuated Total Reflection-Fourier Transform InfraRed) analysis. Larvicidal effects of the nanoliposomes and nonformulated samples were then investigated against Anopheles stephensi. The best-observed efficacy (LC50 5.4 μg/mL) was related to nanoliposomes containing eugenol with a particle size of 109 ± 4 nm. However, LC50 values of the other three nanoformulations were also around 10 μg/mL; all four prepared nanoformulations were thus introduced as natural larvicides for further investigations in the field conditions.

丁香和肉桂精油、丁香酚和肉桂醛纳米脂体对疟疾主要媒介斯氏按蚊的杀灭效果
建议使用杀幼虫剂控制疟疾,特别是在流行地区。然而,由于合成杀幼虫剂的过度使用,蚊子的抗药性和环境污染一直是挑战。本研究首先制备了含有丁香和肉桂精油及其主要成分丁香酚和肉桂醛的纳米脂质体;采用动态光散射(DLS)和衰减全反射-傅里叶变换红外(ATR-FTIR)分析对颗粒大小和成功加载进行了研究。研究了纳米脂质体和非配方样品对斯氏按蚊的杀灭效果。以含丁香酚的纳米脂质体(粒径为109±4 nm)为研究对象,LC50值为5.4 μg/mL。其余3种纳米制剂的LC50值均在10 μg/mL左右;因此,所有四种制备的纳米制剂都被作为天然杀幼虫剂引入,以便在野外条件下进行进一步研究。
