摘要/Abstract

摘要： 从瑞香狼毒（Stellera chamaejasme L.）根乙醇提取物中分离得到了两个二氢黄酮类化合物，结合核磁共振波谱学数据解析，确定其结构为异新狼毒素A（isoneochamaejasmin A）和新狼毒素B （neochamaejasmin B）。并采用实验室活体生物试验方法，研究了这两个化合物对松材线虫（Bursaphelenchus xylophilus）和拟松材线虫（Bursaphelenchus mucronatus）二龄幼虫的触杀活性。结果表明，异新狼毒素A和新狼毒素B对两种线虫均具有一定的触杀活性，且在相同的处理时间和浓度下，新狼毒素B对两种线虫的触杀活性均强于异新狼毒素A。

Abstract: Two biflavonoids were isolated from ethanol extract from the roots of Stellera chamaejasme L.,and their chemical structures were identified as isoneochamaejasmin A and neochamaejasmin B by nuclear magnetic resonance spectral data.The nematicidal activities of the two compounds were tested by bioassay methods with second-stage juveniles (J2s) of Bursaphelenchus xylophilus and Bursaphelenchus mucronatus. The results showed these two biflavonoids exhibited significantly nematicidal activities against both B.xylophilus and B.mucronatus. Neochamaejasmin B displayed better nematicidal activity than isoneochamaejasmin A against two species nematodes under the same conditions.

Key words: Stellera chamaejasme L., Biflavonoids, Bursaphelenchus xylophilus, Bursaphelenchus mucronatus, Nematicidal activity
