| 摘 要： | 为进一步利用和开发大蒜资源，采用V（硝酸）＋V（高氯酸）=4＋1常压微沸条件下消化，用火焰原子吸收法测定不同产地大蒜中的金属元素Na、Ca、Mg、Mn、Cu、K、Zn、Fe、Cr、Cd和Pb的含量。研究了不同元素的仪器最佳工作条件，并做了准确度和精密度的考察。结果表明，大蒜中Na、Ca、Mg、Mn、Cu、K、Zn、Fe、Cr、Cd和Ph的含量分别为236．49、1598．21、612.44, 6.27, 15.48, 12 172.41, 126.88, 64.46, 1.67, 1.75, 2.02; 172.84, 1 243.38, 610.05, 5.32, 13.60, 11689.65, 120. 07, 78.91, 1.75, 2. 04, 1.97; 136. 90, 1467.93, 574. 16, 6. 27,16.90, 12 263.45, 146.34, 116.20, 1.82, 2.17, 2.25 μg·g^-1。加标回收率为96．60％～105．80％，相对标准偏差（n=9）为：0．24％～4．81％，测定方法简单易行，方便快捷。
