| 摘 要： | 采用火焰原子吸收法同时测定了洋槐花中K，Na，Ca，Mg，Pb，Cd，Cu，Mn，Co，Zn，Cr，Fe等12种微量元素的含量。方法的相对标准偏差介于0．07％～2．31％，回收率介于97．0％～107．0％。结果表明，洋槐花中含有丰富的微量元素，其含量K〉Ca〉Mg〉Na〉Fe〉Zn〉Cu〉Mn〉Co〉Pb〉Cr〉CA，说明洋槐花具有较高的营养价值。

| Abstract: | The twelve trace elements in the pagoda flower,including K,Na,Ca,Mg,Pb,Cd,Cu,Mn,Co,Zn,Cr and Fe were determined simultaneously by FAAS.The relative standard deviation of the method is 0.07%-2.31%,and the recovery is 97.0%-107.0%.The analytical results were satisfactory.The results showed that there were comparatively rich metal elements in the pagoda flower.Proportions of the twelve elements are in the order that K>Ca>Mg>Na>Fe>Zn>Cu>Mn>Co>Pb>Cr>Cd.It(implied) that the nutritive value of the pagoda flower is high. |
