摘　　要：采用HNO3/H2O2微波消解制样,利用全谱直读电感耦合等离子原子发射光谱法,分析测定了青海栽培党参中的矿质元素。共检出16种,其中常量元素K、P、S、Mg、Ca、Na的质量分数分别为0.77%、0.39%、0.26%、0.20%、0.18%和0.03%;微量元素Fe、Zn、Cu、Si、Mn、B、Sr、Al的含量分别为9.94、1.44、0.75、15.8、0.77、0.84、2.36、52.5 mg/100 g。By microwave digestion procedure with HNO3/H2O2 to prepare samples,mineral elements of Codonopsis pilosula（Franch.） Nannf.planted in Qinghai were analyzed by inductively coupled plasma optical emission spectrometer（ICP-OES）.The results showed there were 16 mineral elements in it.The mass fractions of some macroelements,K,P,S,Mg,Ca and Na were 0.77%,0.39%,0.26%,0.20%,0.18% and 0.03%,respectively.The contents of microelements,Fe,Zn,Cu,Si,Mn,B,Sr and Al were 49.94,1.44,0.75,15.8,0.77,0.84,2.36 and 52.5 mg/100 g,respectively.
