Abstract A study was carried out on the contents of mineral elements such as Na，K, Ca, Mg，Zn，Cu，Fe，Mn and B in eight different pear varieties by ICP-MS after microwave-assisted digestion. The results indicated that the main elements of the eight pears are similar, but the content of each element is different. The content of K is the highest in the detected pears, followed by Mg, Ca and Na. Compared with the reference value of AIJN (Association of Industry of Juices and Nectars from fruits and vegetables of the European Union), the range scale of K, Mg, and Ca was higher than that of the AIJN, while the content of Na element was lower than that of the AIJN, and other elements content was consistent with it.
