摘　　要：为研究不同品种芋艿中金属元素和微量元素的含量,采用微波消解-火焰原子吸收光谱法测定不同品种芋艿中4种矿质元素含量。结果表明：不同品种芋艿中均含有丰富的Fe、Zn、Cu和Mn 4种矿质元素,且微量元素含量均表现为Fe〉Zn〉Cu〉Mn;其中Fe含量最高,为13.969 3~17.340 8mg·kg-1;Zn含量次之,为4.966 5~5.631 9 mg·kg-1。标准曲线相关系数为0.998 2~0.999 9,加标回收率为98.666 7%~101.646 7%,标准偏差（RSD）小于2%。In order to analyze the contents of metallic and trace elements in various species of Colocasia esculenta （L.） Schoot,Four mineral elements of Colocasia esculenta （L.） Schoot were determined with microwave digestion-flame a-tomic absorption spectrometry. The results showed that 4 kinds of mineral elements in different varieties of Colocasia esculenta （L.） Schoot were rich in Fe, Zn, Cu and Mn, And trace elements content of different varieties content showed Fe〉Zn〉Cu〉Mn. Fe content was the highest,at 13. 969 3-17. 340 8 mg·kg^-1; fellowed by Zn, the content was 4. 966 545. 631 9mg·kg^-1. The correlation coefficient of standard curve was 0. 998 2-0. 999 9,the recovery rate was 98. 666 7%~101. 646 7% ,the standard deviation （RSD） was less than 2%.
