摘　　要：目的研究中药紫石英使用的安全性。方法采用原子吸收分光光度法对紫石英在水煎液和人工胃液中铅、镉、砷、汞、铜的含量分别进行测定。结果紫石英中铅、镉、砷、汞在水煎液的溶出率均高于在人工胃液中溶出率,但在两者中的铅、镉、砷、汞、铜溶出量均远远低于最大允许日摄入量。结论紫石英的临床使用是安全的。Objective To evaluate the security of Fluorite.Methods The atomic absorption spectrophotometry（AAS） was used to determine the content of Pb,Cr,As,Hg and Cu in decoction and artificial gastric juice of Fluorite.Results The dissolution rates of Pb,Cr,As and Hg in Fluorite decoction were all higher than those in artificial gastric juice of fluorite,but the dissolution amount of Pb,Cr,As,Hg and Cu in decoction and in artificial gastric juice of Fluorite were all far below the maximum allowable daily intake.Conclusion Fluorite is safe to be used in clinic.
