摘　　要：采用原子吸收法测定了广东地区20种荔枝中钾、钙、钠、镁、铁、锰、铜和锌8种元素在果肉、果皮和果核中的分布，方法的相对标准偏差介于0．2-1．9％，平均回收率为98．1～104．2％。对不同荔枝品种营养元素含量的变化及其分布的规律性进行了讨论，结果表明元素的分布特征和荔枝品种具有一定相关性，为进一步研究荔枝的药效和保健作用及综合利用提供参考。In this paper, the contents of K, Ca, Na, Mg, Fe, Mn, Cu and Zn was determined in different parts of 20 different breeds of Litchi in Guangdong area, relative standard deviation of the method was between 0.2-1.9%, and recovery was between 98.1-104.2%. Comparison of the concentration and disWibution of those elements was made and Q-type cluster analysis of SPSS was applied for the study of concentration and distribution of those elements in different parts of Litchi. The results showed that the elemental distribution characteristics are related to the breeds of Litchi. It had provided a reference data for the further studies and comprehensive utilization of Litchi.
