目的 研究兰州百合中22种无机元素与种植区域的相关性.方法 用超级微波消解仪处理样品,采用电感耦合等离子体质谱仪测定兰州百合中22种无机元素的含量;对所得数据进行主成分分析,筛选特征元素,并对特征元素与种植区域的相关性进行系统聚类分析.结果 22种无机元素的线性关系良好,均r≥0.9967;定量限为6.5×10-3~26.3517μg·L-1,检出限为2.1×10-3~8.5071μg·L-1;精密度、重复性、稳定性试验的RSD均小于6.82%;平均加样回收率为80.1%~128.8%,RSD为1.81%~6.12%(n=9).锰、铝、钾、钒、铁、铜、钡、镁、锂、锶、镓等为兰州百合的特征元素,其含量水平根据种植区域不同聚为3类.结论 所用方法操作简便、灵敏度高,为兰州百合的地理标志保护和利用提供了依据.
Study on the correlation between the 22 kinds of inorganic elements in Lilium davidii and its planting regions
OBJECTIVE To explore the correlation between 22 inorganic elements in Lilium davidii and its planting regions in Lanzhou.METHODS Samples were digested by super microwave digestion,the contents of 22 kinds of inorganic elements were determined by inductively coupled plasma mass spectrometry,the principal components analysis(PCA)was performed on the data,the characteristic elements were screened,and the correlation between the characteristic elements and planting regions was systematically clustered.RESULTS The linear relationship of 22 inorganic elements was good with r≥0.9967,the limits of quantification were 6.5 × 10-3-26.3517 μg·L-1,the limits of detection were 2.1 × 10-3-8.5071 μg·L-1.RSDs of precision,stability and repeatability tests were all less than 6.82%,and the average recoveries were 80.1%-128.8%,RSD range from 1.81%to 6.12%(n=9).55Mn,27Al,39K,51V,56Fe,63Cu,137Ba,24Mg,7Li,88Sr and 69Ga were the characteristic elements of L.davidii,and the content of characteristic elements was clustered into three categories according to different planting regions.CONCLUSION This method is simple and sensitive,and can provide reference for the protection and utilization of geographical indications of L.davidii.
