摘　　要：用硝酸-高氯酸(4∶1)混合液对厚朴进行消解,然后采用原子吸收光谱法测定厚朴中铜、铁、钙的含量。结果表明,厚朴中含铜4.41Lg/g,含铁55.5 Lg/g,含钙6872.5 Lg/g,加标回收率在93.6%—100.1%之间。该方法测定中药中金属离子的含量方法简便、快速、灵敏。该结果可为进一步研究厚朴的相关药理作用提供参考依据。Flame Atomic Absorption Spectrometry（FAAS） was used to determine the content of copper, iron and calcium in Magnoliae officinalis which is nitrified by nitric acid-perchloric acid system. The results showed that the content of copper is 4.41μg/g,iron is 55.5μg/g,and calcium is 6872.5μg/g,respectively. The addition standard recoveries were between 93.6% and 100.1%. This method being used for the determination of the content of metal ions in traditional Chinese medicine is simple, rapid and sensitive.
