本研究采用Sephedex LH-20凝胶层析柱分离野蚕性信息素粗提物,获得活性馏份。其EAG值达6.8mv,并具田间引诱活性,平均诱捕率为10雄/天/诱捕器。此活性馏份在气谱上有2个主色谱峰,经GC-MS测定得2号色谱峰的分子量为238,基峰m/e 67,M-18=m/e 220,以及其它碎片离子峰完全和蚕蛾醇(反10,顺-12-+六碳二烯醇)一致。以合成蚕蛾醇进行田间引诱试验,亦具引诱活性,诱捕率为2.3～3.5雄/天/诱捕器。证明蚕蛾醇是野蚕性信息素的主成份。
In this study, Sephedex LH-20 gel column chromatography wild pheromone extract was used to obtain the active fraction. The EAG value reached 6.8mv, with the field of lure activity, the average trapping rate of 10 male / day / traps. The active fraction has two main peaks in the gas spectrum. The molecular weight of the No. 2 peak was found to be 238 by GC-MS. The base peaks m / e 67, M-18 = m / e 220 and other fragment ions The peak is completely consistent with momitorin (anti-10, cis-12- + hexadecadienol). In order to synthesize silk moth alcohol field induction test, but also with the lure activity, trapping rate of 2.3 ~ 3.5 male / day / traps. Prove mom moth alcohol is the main component of wild silk pheromone.
