摘　　要：为更高效地从香樟中提取并应用天然樟脑,本文探究了超声时间、溶剂浓度与料液比对香樟中樟脑提取率的影响,同时测定了樟脑的驱虫效果。结果得出:(1)超声波辅助溶剂提取樟脑的提取量显著高于对照组,超声波辅助提取60 min的效果较好;(2)有机溶剂乙醇浓度对樟脑的提取量存在显著影响,适宜的乙醇浓度为60%;(3)樟脑的提取量随料液比的升高而减小,适宜的料液比为1∶15;(4)天然樟脑具有较好的驱虫效果,驱虫率最高达96.30%,樟脑的驱虫率随时间的延长先提高后降低。本研究可为植物萜类化合物的提取和基于驱虫剂的害虫防治提供参考依据。In order to extract natural camphor from Cinnamomum camphora and make use of it more efficiently,the effects of ultrasound time,solvent concentration and solid-liquid ratio on the extraction rate of camphor from C.camphora were studied and the insect repellent effect was measured in this article.The results showed as follows:(1)The extraction amount of camphor with ultrasound assisted solvent was significantly larger than that of the control,and the effect was best with ultrasound assisted extraction for 60 minutes.(2)The concentration of solvent ethanol had a significant impact on the extraction amount of camphor and the appropriate ethanol concentration was 60%.(3)The extraction amount of camphor decreased with the increase of the solid-liquid ratio,and the appropriate solid-liquid ratio was 1∶15.(4)Natural camphor has a good insect repellent effect,with a maximum deworming rate of 96.30%.The deworming rate of camphor increased first and then decreased with time.This study can provide reference for the extraction of plant terpenoids and the pest control based on anthelmintic.
