摘　　要：研究了火焰原子吸收光谱法同时测定大百合中多种微量元素的条件,测定了在不同生长时期大百合中K,Ca,Na,Mg,Fe,Zn,Mn,Cu和Cr等九种元素的含量,方法的相对标准偏差介于0.2%-2.1%之间,平均回收率在97.8%-104.9%之间,分析结果满意。结果表明,大百合中Zn,K,Ca,Mg和Mn等人体必须的生命元素含量较高,提示了大百合具有较高的营养价值。Conditions for simultaneous determination of multi-tract elements in Cardiocrinum giganteum by flame atomic absorption spectrometry were studied.Elements K,Ca,Na,Mg,Fe,Zn,Mn,Cu and Cr in different growth periods of Cardiocrinum giganteum were determined,the relative standard deviation of the method is between 0.2% and 2.1%,and the recovery is between97.8% and 104.9%.Analytical results were satisfactory.The results showed that some elements essential to human such as Zn,K,Ca,Mg and Mn in Cardiocrinum giganteum are abundant,implying that the nutritive value of Cardiocrinum giganteum is high.
