| 摘 要： | 火焰原子吸收光谱法测定了不同生长年限采收的药用植物党参的地上部分和地下部分中Zn的含量。随着生长年限的增长,Zn的含量在党参的地上部分和地下部分均有减少的趋势;地上部分Zn的含量明显高于地下部分。方法平均加标回收率为101.1%,相对标准偏差(RSD)小于2.0%。测定结果为研究元素锌在不同采收年限党参中的分布及含量与党参的药效关系提供了有用的数据。

| Abstract: | Metallic element Zn in different parts of radix codonopsis for different growth years was detected by flame atomic absorption spectrometry.The content of Zn in whole radix codonopsis is decreased with the plant growth year, and the aerial parts show the higher content than the under ground parts. The mean recovery in standard addition is 101.1% with RSD less than 2.0%. The method is rapid and accurate. The results provide a useful data for studying the relationship between the distribution of Zn in different parts of radix codonopsis and its medical effects. |
