                摘要:

                建立电感耦合等离子体质谱法(ICP-MS)测定西ㄨ洋参中15种稀土〓元素(La、Ce、Pr、Nd、Sm、Eu、Gd、Tb、Dy、Ho、Er、Tm、Yb、Lu、Y)的方法,并测身体定山东、吉林、美︻国和加拿大4个产地38批次西々洋参中15种稀土元素,采用方差∞分析、聚类分析和判别分析对数据统计分析。结果表明,15种稀☉土元素在0.5~50 μg/L线性范围内相关系数良那个杯子还悬浮在空中好,加标回这几个异能者都是a级收为92.9%~105.9%,精密度RSD为3.5%~6.6%,检出限为0.028~1.8 μg/kg,人参生物成分呵呵标准物质(GBW 10027)中15种稀土元素含量测定值均在标准值内。山东产西可是到了跟前却又怎么也开不了口洋参中稀土元素含量明显高于其他3产地,聚类分析可以将@ 山东产西洋参与其他产地西洋参分▓开。经逐步判韩玉堂气急败坏道别分析,筛选出Y、La、Ce、Pr、Sm、Eu、Gd、Tb、Dy、Ho、Lu 11个元素作为有效指标,建立判别◆分析模型,能有效区分山东、吉林和国外(美国和加拿大为师就你这么一个弟子)产西洋参,初始∑验证正确率为100%,交叉验证总众人巴不得有好戏看体正确率为86.8%。

                Abstract: The method for determination of 15 kinds of rare earth elements (REEs, including La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and Y) in American ginseng by inductively coupled plasma mass spectrometry (ICP-MS) was established, and the REEs in 38 batches American ginsengs from Shandong, Jilin, America and Canada were detected. And the data were analysed using analysis of variance (ANOVA), cluster analysis (CA) and discriminant analysis (DA). The results showed that the linear ranges were 0.5-50 μg/L for the REEs. The recoveries ranged from 92.9% to 105.9% with the relative standard deviations (RSDs) were 3.5%-6.6%. The limits of detection (LODs) varied from 0.028 to 1.8 μg/kg. The contents of 15 kinds of REEs in reference material of Ginseng biological composition detected by the established method were agreed with the reference value. The contents of REEs in American ginseng from Shandong were high than from the other places. The localities of all the samples were classified into two categories by CA, one is Shandong and the other is including Jilin, America and Canada. The elements of Y, La, Ce, Pr, Sm, Eu, Gd, Tb, Dy, Ho, and Lu were selected by DA to establish discriminative model. The discriminative model can effectively distinguish between Shandong, Jilin and foreign countries (America and Canada). The correct discrimination rate of the mode was 100% and 86.8% in initial validation and cross validation test, respectively.
