Abstract:
[Objective]To analyze the chemical components of the compound essential oil for mosquito repellent,which was composed of Menthae haplocalyx Briq.,Spirodela polyrrhiza(L.)Schleid,Acorus tatarinowii Schott and Rosmarinus offiicinalis L.,and to evaluate its repellent effect.[Methods]The chemical components of the compound mosquito repellent essential oil were analyzed by gas chromatography-mass spectrometer(GC-MS),and the repellent activity of the essential oil against adult Aedes albopictus was evaluated according to the"Efficacy Test and Evaluation of Space Repellent Products(Y-tube Method)".[Results]Fifty-eight main volatile components were identified,accounting for 98.28％of the total components of essential oil,eighteen terpenes(44.99％),nine alkenes(20.27％),five esters(14.07％),eight aromatic hydrocarbons(12.00％),seven alkanes(3.48％),nine alcohols(2.78％),two ketones(0.69％).The percent repellency(PR)of the compound mosquito repellent essential oil against Aedes albopictus was more than 90％on average.[Conclusion]There were many chemical components in the compound mosquito repellent essential oil.There may be a variety of chemical components such as menthol,menthone,α-pinene,etc,which had a repellent effect on Aedes albopictus,and the average repellent effect reached the A level.
