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.

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 ele-ments were detected by flame atomic adsorption spectrometry (FAAS). The results show that the extractive rates of the ele-ments were in the range of 9. 84%-89.07%, and the immersion-residue ratio in the range of 10. 96%-903.4%. Adsorption ration of suspension state was in the range of 3.44%-23.37 %. The recovery ratios by standard addition were in the range of 94. 5%-111.6%, and the relative standard deviations (RSD) were in the range of 0. 29%-2. 47%. The precision and accuracy of deter-mining results are satisfactory.
