摘要
用荧光分光光度法和能量色散X荧光分析法测定了浙江不同地区银杏叶中某些微量元素含量的变化。结果表明:不同地区的银杏叶中微量元素硒、铜、锌、铬、铁和锰的含量范围分别为0.1～2.17×10^(-6),2.8～6.9×10^(-6),6.1～17.1×10^(-6),1.1～6.6×10^(-6),74～399×10^(-6)和15～73×10^(-5).
Some trace elements in Ginkgo biloba L. Leaves of Zhejiang Province were determined byspectrofluorimetric and X-ray fluorimetric methods. The results show that the concentrationrange of Se, Cu, Zn, Cr, Fe and Mn in Ginkgo biloba L. Leaves were 0. 1～2. 17, ×10^(-6)2.8～6.9×10^(-6), 6.1～17.1×10^(-6), 1. 1～6. 6×10^(-6), 74～399×10^(-5)和15～73×10^(-6) respectively.
