摘要
目的:探究钻山风中无机元素的含量,为钻山风药材的资源开发和安全使用提供科学依据.方法:采用微波消解-ICP和ICP-MS测定Li、Be、Ti、V、Cr、Co、Ni、Cu、Zn、Ga、As、Sr、Cd、Sn、Sb、Ba、Hg、Tl、Pb、Bi、Mg、K、Fe、Mn、Ca 25种无机元素的含量.结果:钻山风中无机元素含量较高的依次为Ca、K、Mg、Ti、Zn、Fe、Sr、Ba,2批样品中有害元素Cd检出含量超过《药用植物及制剂外经贸绿色行业标准》规定的限量标准值0.3mg/kg,其内梅罗综合污染风险评价为轻污染,其他3批样品的内梅罗综合污染风险评价为安全.结论:钻山风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.
Abstract
Objective:Exploring the content of inorganic elements in Diamond Mountain Wind provides scientific basis for the resource development and safety of Diamond Mountain Wind medicinal herbs. Method:Microwave digestion ICP and ICP-MS were used to determine the content of 25 inorganic elements,including Li,Be,Ti,V,Cr,Co,Ni,Cu,Zn,Ga,As,Sr,Cd,Sn,Sb,Ba,Hg,Tl,Pb,Bi,Mg,K,Fe,Mn,Ca etc. Result:The higher content of inorganic elements in Diamond Moun-tain Wind is Ca,K,Mg,Ti,Zn,Fe,Sr,Ba in sequence. The detection content of harmful element Cd in two batches of samples exceeds the limit value of 0.3 mg/kg specified in the "Green Industry Standard for Pharmaceutical Plants and Prepa-rations in Foreign Trade",and the comprehensive pollution risk assessment of Nemero is light pollution. The comprehen-sive pollution risk assessment of Nemero in the other three batches of samples is safe. Conclusion:Diamond Mountain Wind contains rich inorganic elements,which can provide scientific basis for its clinical medicinal safety.
