Abstract：A study was carried out on the contents of nutritional elements such as K, Fe, Zn, Ca, Cu, Mg and Mn in three different red pear varieties, namely Meirensu, Hongsucui and Mantianhongs, by flame atomic absorption. The results indicated that the linear relationships for different elements within the limits of working curves are good, and the range of recovery is 98%-104%, hence showing that the results asre satisfactory. There are abundant nutritional elements in fruits of the three different red pear varieties, meaning that they all have a relatively high nutritive value. In fruits of the three red pear varieties, the content sequence of different nutritional elements was found to be K>Fe>Zn>Ca>Cu>Mg>Mn. In fruits of the three different red pear varieties, the content sequence of K, Zn, Mg and Mn was Meirensu>Hongsucui>Mantianhong; the content sequence of Fe and Cu was Hongsucui>Mantianhong>Meirensu; and the content sequence of Ca was Mantianhong>Hongsucui>Meirensu; and the total content sequence of seven nutritional elements was Hongsucui>Meirensu>Mantianhong.
