The contents of trace elements, including aluminum, barium, beryllium, calcium, cobaltium, chromium, copper, iron, potassium, lanthanum, lithium, magnesium, manganese, sodium, nickel, phosphorus, lead, sulfur, silicon, titanium, vanadium, and zinc, were determined by ICP-AES. The mean concentrations of the 22 elements were as follows: K>Ca>Mg>Fe>Al>Na>S>P>Ba>Ti>Mn>Zn>Sr>Cu>Ni=Cr>Pb>V>Li=La>Co>Be. Principal components analysis of SPSS was applied to study the characteristic elements in Salvia roborwskii. Five principal components which accounted for 89.288% of the total variance were extracted from the original data. The first factor accounted for 56.401% of the total variance, which meant that aluminum, barium, beryllium, calcium, and cobaltium were the characteristic elements in S. roborwskii. This useful new method was used to evaluate the quality of S. roborwskii, and to provide the scientific foundation for its utilization and further research.
采用 ICP-AES 法测定了微量元素(包括铝、钡、铍、钙、钴、铬、铜、铁、钾、镧、锂、镁、锰、钠、镍、磷、铅、硫、硅、钛、钒和锌)的含量。22 种元素的平均浓度为:K>Ca>Mg>Fe>Al>Na>S>P>Ba>Ti>Mn>Zn>Sr>Cu>Ni=Cr>Pb>V>Li=La>Co>Be。采用 SPSS 主成分分析对岩黄连特征元素进行研究,从原始数据中提取了 5 个占总方差 89.288%的主成分,其中第一个因子占总方差的 56.401%,说明铝、钡、铍、钙、钴为岩黄连的特征元素。该方法为岩黄连质量评价提供了新的思路和方法,为其开发利用和进一步研究提供了科学依据。
