摘　　要： 为了寻找新的萜类驱避剂,以羟基香茅醛为原料,合成羟基香茅醛二甲缩醛、羟基香茅醛乙二醇缩醛、羟基香茅醛1,3-丙二醇缩醛和羟基香茅醛1,2-丙二醇缩醛,用红外光谱IR、质谱MS分析其结构,对羟基香茅醛1,2-丙二醇缩醛还进行了1HNMR及13CNMR分析。按国标GB/T13917.9-2009测定了它们对白纹伊蚊Aedesalbopictus、中华按蚊Anopheles sinensis及淡色库蚊Culexpipiens的驱避活性。结果表明:10%(质量分数)羟基香茅醛二甲缩醛和羟基香茅醛1,2-丙二醇缩醛对中华按蚊的驱避时间均达到国标B级;羟基香茅醛1,2-丙二醇缩醛还对其他的蚊虫具有驱避作用,20%(质量分数)羟基香茅醛1,2-丙二醇缩醛对白纹伊蚊的驱避时间超过国标B级;10%(质量分数)羟基香茅醛1,2-丙二醇缩醛对淡色库蚊的驱避时间超过国标A级。这些结果说明它们对不同蚊种驱避活性的差别,为不同场合的驱蚊需要提供了理论基础。 In order to seek novel terpenoid repellent,4 acetal derivatives of hydroxycitronellal,i.e.,hydroxycitronellal dimethyl acetal,hydroxycitronellal 1,2-ethandiol acetal,hydroxycitronellal 1,3-propanediol acetal and hydroxycitronellal 1,2-propanediol acetal,were synthesized in this study.Their structures were characterized using IR and MS,1H NMR,and 13C NMR（for hydroxycitronellal 1,2-propanediol acetal only）.Repellencies against Aedes albopictus,Anopheles sinensis and Culex pipiens were examined using the method described in GB/T 13917.9-2009.The results showed that the repellent activity of 10%（mass） solution of both hydroxycitronellal dimethyl acetal and hydroxycitronellal 1,2-propanediol acetal against A.sinensis reached grade B as defined in GB/T 13917.9-2009,and that of a concentrated solution（20% in mass） of hydroxycitronellal 1,2-propanediol acetal against A.sinensis even approached to grade A.Hydroxycitronellal 1,2-propanediol acetal also showed the repellency to other mosquitoes as well：the repellent activity of 20%（mass） solutions against A.albopictus and that of 10%（mass） solutions against C.pipiens exceeded the grades B and A,respectively.These results indicate that the repellent activity difference against different mosquito species offers the theoretical basis for using the repellents in different situations.
