Abstract: OBJECTIVE:The in vitro micronucleus test was applied to evaluate genotoxicity of the traditional Chinese medicine Panax notoginseng extracting solution. METHODS:The Chinese hamster lung cell line (CHL) were treated with Panax notoginseng extracting solution which was prepared by soaking with alcohol repeatedly at three concentrations (0.625,1.250,2.500 mg/mL). Cell toxicity was determined by the neutral red uptake test. Genotoxicity was determined with and without the S9 metabolic activation via the in vitro cytokinesis-block micronucleus test. Cyclophosphamide and mitomycin C were used as the positive controls,and MEM was used as the negative control. RESULTS:The neutral red uptake test showed that the 2.500 mg/mL concentration of Panax notoginseng extracting solution induced OD value decreased significantly compare with negative control (P < 0.05) which indicates that the cell survival rate was 80.3%. The frequencies of micronuclei in the three concentrations of 0.625,1.250,2.500 mg/mL of Panax notoginseng extracting solution were 17‰,16‰,16‰ in the presence of +S9. In the absence of S9,the frequencies were 17‰,15‰,16‰ which were not significantly different from the negative control (+S9 16‰、-S9 15‰,P > 0.05). CONCLUSION:Panax notoginseng extracting solution did not show genotoxicity under our study conditions.
