摘要 目的:探究蕲蛇和酒蕲蛇中无机元素的含量,为蕲蛇药材的资源开发和安全使用提供科学依据。方法:采用ICP和ICP-MS测定Li、Be、Ti、V、Cr、Mn、Fe、Co、Ni、Cu、Zn、Ga、As、Sr、Mg、K、Cd、Sn、Sb、Ca、Ba、Hg、Tl、Pb、Bi 25种无机元素的含量。结果:蕲蛇和酒蕲蛇中存在丰富的无机元素,蕲蛇中Be、Sb、Bi元素未检出,酒蕲蛇中Be、Sb元素未检出。Cu、Pb、Cd、As检出含量值均远小于《药用植物及制剂外经贸绿色行业标准》规定的限量标准值,酒蕲蛇中Hg含量为0.332~0.463 mg/kg,超过规定限值0.2 mg/kg;蕲蛇的重金属及其有害元素内梅罗综合污染指数小于0.7,评价为优良;酒蕲蛇的重金属及其有害元素内梅罗综合污染指数为1.39,评价为轻污染。结论:蕲蛇和酒蕲蛇中含有丰富的无机元素,可为其临床药用安全性提供科学依据。 Objective:To investigate the content of inorganic elements in Agkistrodon acutus and Agkistrodon acutus broiled by alcohol,and to provide scientific basis for the development and safety of Agkistrodon acutus medicinal resources.Method:Microwave digestion ICP and ICP-MS were used to determine the content of 25 inorganic elements,including Li,Be,Ti,V,Cr,Mn,Fe,Co,Ni,Cu,Zn,Ga,As,Sr,Mg、K、Cd、Sn、Ca,Ba,Hg,Tl,Pb,Bi,etc.Result:There are abundant inorganic elements in the Agkistrodon acutus and Agkistrodon acutus broiled by alcohol.Be,Sb,and Bi elements were not detected in the Agkistrodon acutus,while Be and Sb elements were not detected in the Agkistrodon acutus broiled by alcohol.The detected content values of Cu,Pb,Cd and As are far less than the limit standard values specified in the"Green Industry Standard for Foreign Trade and Economic Cooperation of Medicinal Plants and Preparations".The Hg content in the wine Agkistrodon acutus broiled by alcohol is 0.332~0.463 mg/kg,exceeding the specified limit value of 0.2 mg/kg.The Nemero comprehensive pollution index of heavy metals and harmful elements in Agkistrodon acutus is less than 0.7,which is evaluated as excellent.The Nemero comprehensive pollution index of heavy metals and harmful elements in Agkistrodon acutus broiled by alcohol is 1.39,which is evaluated as light pollution.Conclusion:Agkistrodon acutus and Agkistrodon acutus broiled by alcohol contain abundant inorganic elements,which can provide scientific basis for their clinical medicinal safety.
