目的 建立电感耦合等离子体-质谱(ICP-MS)法测定不同产地玉竹和黄精中Na、Mg、Al、K、Ca、Mn、Fe、Ni、Cu、Zn、V、Cr、Co、Ga、As、Se、Rb、Sr、Ag、Cd、Cs、Ba、Tl、Pb、U、Hg 的含量.方法 40 批样品经微波消解后,采用ICP-MS法测定各无机元素含量,绘制其图谱,主成分分析(PCA)、正交偏最小二乘法判别分析(OPLS-DA)进行多变量统计分析.结果 2种药材主要无机元素均为K、Mg、Ca、Al、Fe、Mn、Na,并存在正相关性.各无机元素峰形分布相似,其图谱具有特征性.不同产地2种药材可区分,Sr、Se、V、Cd、Al、Ga、Fe、Cr、Ni、Co是特征无机元素.Hg、Cr含量分别在5、6批样品中超标.结论 该方法稳定可靠,可有效...

AIM To establish an inductively coupled plasma-mass spectrometry(ICP-MS) method for the content determination of Na, Mg, Al, K, Ca, Mn, Fe, Ni, Cu, Zn, V, Cr, Co, Ga, As, Se, Rb, Sr, Ag, Cd, Cs, Ba, Tl, Pb, U and Hg in Polygonati odorati Rhizoma and Polygonati Rhizoma from different growing areas.METHODS Forty batches of samples were digested by microwave, after which ICP-MS was applied to determining the contents of various inorganic elements, whose spectra were drawn, principal component analysis(PCA) and orthogonal partial least squares discriminant model analysis(OPLS-DA) were used for mul...
