摘　　要： [目的]筛选紫茎泽兰(Eupatorium adenophorum Spreng)中除草活性物质的较佳提取方法。[方法]采用索氏提取法、超声波提取法和浸提法3种常用提取方法制备紫茎泽兰提取物,并采用种子萌发法研究了3种提取方法所得紫茎泽兰提取物的除草活性。[结果]索氏提取法对紫茎泽兰的提取率最高,为(22.54±0.48)%;紫茎泽兰索氏提取法所得提取物的除草活性较强。[结论]索氏提取法是紫茎泽兰中除草活性物质的较佳提取方法。 [Objective] The paper was to screen the better extraction method for herbicidal active substances of Eupatorium adenophorum.[Method] Three common extraction methods,Soxhlet extraction,ultrasonic extraction and conventional extraction methods,were used to prepare E.adenophorum extracts,and the herbicidal activity of E.adenophorum extracts extracted by 3 methods was studied by seed germination method.[Result] The extraction rate of Soxhlet extraction was the highest of（22.54±0.48）%,and the herbicidal activities of E.adenophorum extracted by Soxhlet extraction was relatively stronger.[Conclusion] Soxhlet extraction was the better extraction method for herbicidal active substances of E.adenophorum.
