摘　　要：［目的］建立火焰原子吸收光谱法测定木通中钙、镁、 铁、锌、铜、锰元素含量的方法。［方法］用浓硝酸微波消解样品，采用光焰光度法测定。［结果］木通中含有钙 17.0 mg/g，镁3.13 mg/g，铁 1.41 mg/g，锌0.148 mg/g，铜0.025 9 mg/g， 锰 0.588 mg/g。RSD为2.3%-9.2% ，回收率为95%-108%。［结论］此方法简单、准确，结果令人满意。[ Objective ] The research aimed to establish a determination method of Ca , Mg , Fe , Zn, Cu and Mn in Akebia quinata by microwave digestion-flame atomic absorption spectrometry. [ Method] The samples were diluted by microwave digestion with HNO3 and the contents were determined by calibration curve method. [ Result ] The contents of Ca, Mg, Fe, Zn, Cu and Mn in A. quinata Were 17.0, 3.13, 1.41,0. 148, 0.025 9 and 0. 588 mg/g resp. RSD was 2.3% - 9.2% and the recovery was 95% - 108%. [ Conclusion] The method is simple, accurate and satisfying.
