摘      要：[Objective] The research aimed to analyze the inhibitory mechanism of Sophora japonica n-hexane extract which significantly inhibited Microcystis aeruginosa in the prior research.[Method] *** n-hexane extract was used to treat *** inspecting chlorophyll a content,protein content,cell membrane permeability and superoxide dismutase（SOD） activity,the inhibitory mechanism of *** n-hexane extract on *** was analyzed initially.[Result] *** n-hexane extract destroyed the cell membrane system of ***,and increased the cell membrane *** contents of chlorophyll a and protein respectively declined to 10% and 50% of that in the control group after cultivated for 7 d,which indicated the photosynthetic reaction system of *** was *** addition,under the effect of *** n-hexane extract,SOD activity of *** increased in the early period and decreased in the latter period.[Conclusion] The possible inhibitory mechanism of *** n-hexane extract on *** was destroying the cell membrane to increase the membrane permeability;destroying the photosynthetic reaction system to decrease the contents of photosynthetic pigment and protein;making SOD activity showing the phased variation.
