[Analysis of the microelements contents in melons and fruits of Xinjiang].
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 x kg(-1), the strontium quantity in jujubes is 8.62 mg x kg(-1) and Chinese-date contains strontium 8.62 mg x kg(-1) in Hetian area; and that in the Kuerle area the pomegranate is potassium 687 mg x 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 x kg(-1)), and in the watermelon of Wujiaqu, the pericarp (54.19 mg x kg(-1)) take place higher than in the pulp (48.69 mg x kg(-1)) by 1.11 times. The result can provides the conference for studies of melons and fruits foodstuff studies in Xinjiang.
