Abstract: | [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. |
