Abstract
Juvenile hormone (JH) was determined by ligation, organ removal and transplantation and bioassay.. JH is an important substance in the process of insect growth and development, including the development, polymorphism, the key to the regulation of diapause, the coordination of reproductive maturity, and the production of pheromone. Therefore, the precise determination of the structure of the amount of insects produced by different physiological states is the key function of the determination of the amount of insects.. In 1967, Roller et al. Using MS and nuclear magnetic resonance (GC-MC) to complete the structure identification of JH workers, and it is the important method for the modern instrument analysis to be applied to JH.. With the development of radio immunity and chromatographic analysis, the method of JH assay is gradually mature.. At present, the main methods of JH include: chemical analysis, HPLC, gas chromatography, mass spectrometry (GC-MC), radioimmunoassay, juvenile hormone binding protein, etc.. Among them GC-MS - MS is the JH identification method, the accuracy and the credibility are high, is the only objective method for the unknown species identification of JH. But the existing GC-MS method is a chemical ionization method.
In this paper, using a triple quadrupole tandem mass spectrometer, scanning method of multiple reaction monitoring, JH synthesis glands pharyngeal side of in vitro culture and GC-MS-MS analysis method combined with, and established a set of accurate and reliable JH biosynthesis detection method. The establishment of this method will be helpful for the biological activity testing of JH biosynthesis inhibitors..
