摘　　要：目的:进行灵芝及其类似品中微量元素的分析研究。方法:采用湿法消解前处理,电感耦合等离子发射光谱(ICP-AES)法测定。结果:灵芝及其类似品中含有丰富的矿物元素,具有较高的K、Ca、P、Mg含量和低Na含量,并含有丰富的微量元素Fe、Zn、Cu、Mn、Ni、Co、Cr元素,但微量营养元素Se、Ge、Mo和重金属元素Hg含量很低,灵芝及其类似品中存在的微量As元素应包括无机As和有机As,微量的As元素对抑制肿瘤可能是有利的。结论:灵芝及其类似品中,微量元素分布趋势基本相同,其中黑芝、紫芝、菌种赤芝、1号赤芝显示更优的营养元素含量分布特征。Objective：To analyze multi-trace elements from Ganoderma and its analogues.Methods：Samples was pretreated by wet digestion and trace elements was determined by inductively coupled plasma-atomic emission spectrometry（ICP-AES）.Results：Mineral elements were rich in Ganoderma and its analogues,with high contents K,Ca,P and Mg and low content Na,as well as rich trace elements：Fe,Zn,Cu,Mn,Ni,Co and Cr,but trace elements Se,Ge,Mo,and heavy metal Hg were at low levels.Ganoderma and its analogues included inorganic and organic As,trace element As may be beneficia to inhibit tumor.Conclusion：The distribution trend of trace elements was basically the same in Ganoderma and its analogues,some of them,such as：G.atrum,G.sinense,G.lucidum（strain culture）,and No.1 G.lucidum showed superior nutrient elements contents compared with other.
