Abstract
[Objective] The research aimed to study the relationship between structure and insecticidal activity of mesaconitine.[Method] Seven derivatives were synthesized from mesaconitine,their structure were characterized by EI-MS and NMR;The insecticidal activity of mesaconitine and its seven derivatives were tested against Nilaparvata legen,Mythima separate,Tetranychus cinnabarnus and Aphis medicagini.[Result] The results indicated that compound A,B, C,F,G exhibited insecticidal activity,of which F and G were significant to Nilaparvata legen.[Conclusion] The structure-insecticidal activity relationship studies mentioned above showed that 3-OH,13-OH and 15-OH of mesaconitine were beneficial to the insecticidal activity.The inorganic salts of mesaconitine were exhibited high insecticidal activity against Nilaparvata legen.
