| 摘 要： | 照传统煎煮法对中药灯台叶中铜、锌、铁、镁、钙、铬、锰和镉8种元素进行提取;用微孔滤膜分离提取液中的可溶态与悬浮态，利用大孔吸附树脂柱对可溶态中的有机态与无机态进行分离;采用火焰原子吸收光谱法对各种形态中的8种元素进行测定。结果显示，灯台叶中8种元素的总提取率为9.84%～89.07%，浸留比为10.96%～903.4%，悬浮态颗粒吸附率为3.44%～23.37%。该法对各元素的加标回收率为94.5%～111.6%;相对标准偏差在0.29%～2.47%之间，测定结果的精密度和准确度令人满意。

| Abstract: | The eight elements,Cu,Zn,Fe,Mg,Ca,Cr,Mn and Cd,in the leaves of Alstonia scholaris were extracted based on traditional analytical flowchart program and separated into water-soluble state and suspension state by micro porous filtering film.The water-soluble state was divided into organic state and inorganic state based on macro porous adsorption resin.The elements were detected by flame atomic adsorption spectrometry(FAAS).The results show that the extractive rates of the elements were in the range of 9.84%-... |
