摘要：狼毒是我国北方普遍生长的一种有毒植物,其根是一种传统中药材。20世纪90年代中期以来,作为一种植源性农药资源,狼毒的开发研究受到重视。本研究表明不同狼毒根提取物都能表现出一定的生物活性,利用狼毒根水浸液与乙醇提取物对舞毒蛾幼虫的拒食作用最高达99%,7d的校正死亡率最高达100%,室内毒力测定中防后5d的校正死亡率最高达100%;不同有机溶剂对狼毒根乙醇提取物萃取分离得到的有效成分对油松毛虫的拒食作用最高达92 39%,7d的校正死亡率最高达100%。不同有机溶剂的萃取物对杨树溃疡病原菌表现出抑制生长的作用,而对仙客来尖镰孢基本没有效果。
The root of Chinese stellera (Stellera chamaejasme) was a traditional Chinese medicine, which was a toxic plant grown widely in north of China. Since the medium of 1980s, researchers emphasized Chinese stellera as a kind of resource of plant pesticides. The result of bioassay illustrated that the different extracts from root of Chinese stellera possess certain biological activity. 99% larvae of Lymantria dispar refused to feed on the leaves immersed by water extract and SCEE of the root, which caused the 100% larvae death correctively. In the experiment of evaluating toxicity, the larva had 100% corrective mortality after dealing with the extracts 5 d later. The antifeeding effects rates reached 92.39% when the larva of Dendrolimus tabulaeformis was fed on the extract of SCEE with different organic solvents, meanwhile the corrective mortality reached at 100% after 7 d. The different extracts by different organic agents could restrain the growth of Botryosphaeria dothidea in artificial medium, but had no obvious effects on the growth of Fusaruum oxysporum.
