摘 要:目的:对雄黄及微生物炮制液砷形态和毒性进行分析,旨在阐明雄黄炮制液中毒性和砷形态的关系。方法:采用毛细管电泳法对三种雄黄微生物炮制液中砷的形态进行分离分析;以常规炮制雄黄作对照,分别测定三种雄黄微生物炮制液和亚砷酸的急性毒性。结果:雄黄微生物炮制液含有三种形态的砷(iAsⅢ、iAsV和MMAV),而且其所含砷的形态、含量随炮制方法变化差异显著,MMAV随着含量的增高,其毒性明显降低。结论:雄黄炮制后砷的形态和毒性密切相关。Objective:To analyze speciation and toxicity of arsenic in realgar bioleaching solution,and to explore its possible relation between speciation and toxicity.Methods:Capillary zone electrophoresis(CZE)can be used quickly and simply onto the simultaneous separation and quantitative determination of the speciation of arsenic in realgar bioleaching solution.The effects of three different realgar bioleaching liquids on the acute toxicity level of rat were also investigated as well.Parallel experiments with traditional processing realgar via gastric irrigation were conducted for comparison.Results:There are three different arsenic species in realgar bioleaching solution(iAsⅢ、iAsV和MMAV),and the processing method largely affected speciation and toxicity of arsenic of it.It was found that the toxicity level was decreased through increasing the amount of MMAV.Conclusion:These results indicate that the species of arsenic may be tightly relationship to its toxicity in realgar bioleaching solution.
