摘　　要：经湿法微波消解制样,利用全谱直读电感耦合等离子体-发射光谱法(ICP-OES)对青海野生黄蘑菇中的矿质元素进行全面详细的分析测定。测定结果表明,野生黄蘑菇中含有K、P、S、Mg、Ca、Fe、Al、Na、Zn、Cu、Mn、Cd、Ti、B、Ba、Cr、Sr 17种矿质元素,常量矿质元素中K、P、S的含量较高,微量元素中,Fe、Zn和Cu含量丰富,同时含有一定量的Cd元素,未检出Se元素。分析方法回收率在92.2%—108.8%之间,RSD为0.79%—9.05%。该方法简单、快速、可靠、灵敏度高,且多元素可同时测定,能满足实际样品分析要求。分析结果可为青海野生黄蘑菇的开发利用研究提供参考。After prepared samples by wet digestion procedure,the mineral elements in wild yellow fungus from Qinghai province were completely determined by inductively coupled plasma optical emission spectrometry（ICP-OES）.The results showed there were 17 mineral elements in this kind of fungus.They were K,P,S,Mg,P,Fe,Al,Na,Zn,Cu,Mn,Cd,Ti,B,Ba,Cr and Sr.Among them,K,P and S were richer in macroelements,while Fe,Zn and Cu were richer in microelements.The recovery of this method was from 92.2% to 108.8%,and the RSD of the method was between 0.79% and 9.05%.The method is simple,rapid and credible with high sensibility.The method can be used to analyze multi-elements in the same time and fulfill the analysis of actual samples.These results provide some reference in developing wild yellow fungus from Qinghai.
