为了评价杭白菊等12种饮用干花的营养价值,在已有的实验数据基础上,结合主成分分析方法,采用SPSS13.0软件,计算了12种饮用干花中的微量元素之间的相关矩阵、载荷系数矩阵及各主成分的得分与综合得分. 结果表明各主成分其主要作用的元素分别是: 第一主成分是Cr、Cu和Mg; 第二主成分是As、Zn和Fe;第三主成分是Cd、Ca和Mg;第四主成分是Pb、As和Cr. 根据综合得分可知桃花、野菊花、黄山贡菊的营养价值最高,为选择营养价值更高的饮用干花给出了科学的理论依据.

To evaluate the nutritional value of Dendranthema morifolium and other 11 kinds of dried flowers, the principal component analysis method was used to calculate the correlation matrix, load factor matrix, each principal component score and the comprehensive scores of trace elements in the flowers by using soft-ware SPSS13.0 based on the existing experimental data. Results showed that the first main principal compo-nents are Cr, Cu and Mg; the second main components are As, Zn and Fe; the third main components are Cd, Ca and Mg , and the forth main components are Pb, AS, Cr. According to the comprehensive scores, peach blossom, chrysanthemum indicum and Huangshan Gongju have highest nutritional value, which pro-vided scientific evidence for choosing more nutritious drinking dry flower.
