Keyword:  萝卜微量元素含量测定;
Abstract: [目的]测定白萝卜、胡萝卜、红萝卜中Cu、Fe、Mn 3种微量元素的含量.[方法]采用硝酸和高氯酸(4+1)分解样品,火焰原子吸收光谱法(FAAS)测定,对不同萝卜中微量元素Cu、Fe、Mn的含量进行测定.[结果]3种萝卜中3种微量元素含量存在差异,其中白萝卜和胡萝卜中元素含量为:Fe>Cu>Mn,红萝卜中上述元素含量为:Fe>Mn>Cu.回收率在93.0%~106.0%,R SD< 1.01.[结论]3种萝卜中3种微量元素Cu、Fe、Mn含量丰富且存在一定差异,研究结果为进一步研究并开发其药用价值与有关微量元素关系提供了一定的参考.
