摘　　要：用超声波硝酸浸提法获取4种明矾炮制药材的提取液,次灵敏线石墨炉原子吸收法(GFAAS)直接测定其中铝含量。优化提取条件及进行方法学考察;并且与湿法消解法进行比较。结果表明本法是一种快速测定明矾炮制药材中铝含量的准确方法。Extracted solutions in four Alum processing Chinese herbal Medicines were obtained by ultrasonic and acid extraction method. Aluminum in the solutions was determined by Graphite furnace atomic absorption spectrometry at Hypo -sensitive wavelength. Extraction conditions were optimized, Methodological investigation on determination was also studied. The result was compared with wet digestion method, which shows that this is a quick and accurate method for determination of aluminum in some Alum processing Chinese herbal medicines.
