摘　　要：利用原子吸收法和原子发射法对新疆十一类瓜果八种微量元素进行检测,并与中国生物标准进行比较分析。结果发现,新疆和田地区苹果含锌66.75mg.kg-1、含钾819.2mg.kg-1、含锰4.657mg.kg-1,大枣含锶8.62mg.kg-1;新疆库尔勒地区石榴含钾687mg.kg-1;新疆哈密地区大枣锰、锌、锶、钙、铁、镍和钾七种微量元素含量均高出各相应的中国生物标准;在十一类瓜果中铜元素含量均低于中国生物标准;八种微量元素含量平均值在新疆库尔勒石榴、新疆和田苹果、新疆哈密大枣中表现很高(分别为91.82,121.5,275.3mg.kg-1);在新疆五家渠种植的西瓜中八种微量元素表现出果皮中平均含量(54.19mg.kg-1)是瓤中平均含量(48.69mg.kg-1)的1.11倍。其研究结果对新疆瓜果营养成分研究提供科学的基础数据。Through the atom absorption and emission spectrum analysis, it is detected 8 trace elements contents in eleven species of melons and fruits in Xinjiang. On comparative analysis with biological standard of China, it is found that the zinc quantity in apples is 66.75 mg· kg^-1 , the strontium quantity in jujubes is 8. 62 mg· kg^-1 and Chinese-date contains strontium 8. 62 mg· kg^-1 in Hetian area; and that in the Kuerle area the pomegranate is potassium 687 mg· kg, in Hami Territory Chinese-date contains manganese, zinc, strontium, calcium, iron, potassium and nickel, all of them are more over the national biological standard. The contents of copper in eleven species of melons and fruits are lower than the biological standard of China. The average contents of 8 kind microelement in the pomegranate of Kuerle, in the apples of Hetian, the Chinese-date of Hami are very high （respectively to be 91.82, 121.5 and 275.3 mg · kg^-1 ）, and in the watermelon of Wujiaqu, the pericarp （54.19 mg · kg^-1） take place higher than in the pulp （48. 69 mg· kg^-1） by 1.11 times. The result can provides the conference for studies of melons and fruits foodstuff studies in Xinjiang.
