摘　　要：研究了人参黑斑病菌毒素的主要化学成分、分子结构及毒素量效关系。经过乙酸乙酯萃取的粗毒素再经硅胶吸附色谱、制备液相色谱等进行分离、纯化,再经生物测定,确定了成分相对较少的人参黑斑病菌毒素的有效成分的官能团,并采用气质联机(GC-MS)的方法初步确定人参黑斑病菌毒素的主要成分为邻苯二甲酸丁酯。The experiment was conducted to isolate the impure toxin from Alternaria panax to clarify the chemical composition, molecular structure and dose-effect relationship of toxin of Ginseng black spot pathogen Alternaria panax by silica gel ad-sorption chromatograph and preparative chromatography , respectively .Composition and molecular structure of the toxin was identified as butyl benzene o-dicarboxylate by Gas Chromatography-Mass Spectrometer .
