Abstract

This study attempted to evaluate the physicochemical characteristics of essential oil nanoliposomes from three plants by two preparation methods including thin film sonication and heating. Also, the durability of fumigation toxicity of the essential oil nanoliposome and pure essential oil of Mentha pulegium against Tribolium castaneum Herbst adults were compared. The smallest mean size of the nanoliposome was prepared by the thin film sonication method (P<0.05). The encapsulation efficiency of the nanoliposome was higher than 96%. Nanoliposmes prepared by using two methods showed high stability during storage. The release profile of essential oils at the heating method showed that the essential oil diffusion from the nanoliposome was in the following order: Mentha pulegium > Ferula gummosa > Zattaria multiflora. These findings indicate that both preparation methods had the same effect on the formation of nanoliposomes, their characteristics, and their storage stability. The durability of fumigation toxicity of the nanoliposome M. pulegium essential oil had a significant effect on mortality of T. castaneum adults in comparison with pure essential oil of this plant. The result showed that nanoliposome encapsulation of M. pulegium essential oil significantly increased fumigation toxicity against T. castaneum. Therefore, essential oil encapsulation into a nanoliposome carrier can potentially be used in pest management. © 2020 Trans Tech Publications Ltd, Switzerland.
