摘　　要：[目的]为了明确菌液的理化性质与杀线活性之间的关系。[方法]采用紫外吸收光谱法初步探索了利用物理化学方测定杀线虫活性的可能性。[结果]将菌液紫外光谱图分析结果与该组分的生物测定结果进行初步比较,显示波长在291 nm处的吸光度值与杀线虫活性生物测定的结果之间存在较好的相关性。[Aims] The aim was to determine the relationship between the physicochemical property and the nematicidal activity of the fermentation liquor. [Methods] This paper explored the possibility of determination of activity by the physical and chemical method using the ultraviolet absorption spectrometry. [ResultsI The analysis results of UV-spectra were compared with bioassay, which showed that there was good correlation between the Abs（at the 291 nm or so） in UV of the ferment-ation liquid and bio-assay.
