Abstract:

To explore the mosquito repellent effect and the therapeutic properties of allergic skin itching of 1, 8-cineole, the repellent activity of 1, 8-cineole against Aedes albopictus under different doses was studied by the Y-tube olfactory test. The antipruritic effect of 1, 8-cineole (φ=5%, prepared with olive oil) was studied in an animal model of mice skin scratching response induced by 4-aminopyridine(4-AP). The results show that 1, 8-cineole at the dose of 4.0 μL repels 100% of A. albopictus in the initial 4 minutes and the repellent effect of 1, 8-cineole against A. albopictus increases in a dose-dependent manner. In addition, mice experiments show that the scratching frequency of mice treated with 1, 8-cineole reduces significantly within 10 minutes; and the contents of serum interleukin 31 (IL-31), platelet activating factor (PAF), serotonin (5-HT) and histamine in the skin filtrate of mice treated with 1, 8-cineole are significantly reduced compared with the model group. The pathological sections show that no edema in the skin of mice in the 1, 8-cineole group is observed and the infiltration of inflammatory cells is inhibited. In conclusion, when the concentration of 1, 8-cineole reaches a certain value, it shows obvious repellent effect on A. albopictus. 1, 8-cineole also has a significant antipruritic effect through the mechanism of antagonizing the release of IL-31, PAF, 5-HT, as well as the mediator of itching, histamine.

Key words: 1,8-cineole, mosquito-repellent activity, antipruritic effect
