Abstract: The contents of 12 mineral elements in the eggs among Tibetan chicken of Aba prefecture were determined by microwave digestion-inductively coupled plasma atomic emission spectrometry（ICP-OES）. The result shows that the contents of Ba,Ca,Cu,P,Mn in the egg shell among the three strains of Tibetan chicken of Aba prefecture were not significantly different （P>0.05）,the contents of Ca and P were high,accounting for more than 99% of the total content,while the content of Si,K,Ba,Fe slightly higher than other mineral elements;The contents of 12 mineral elements in the egg white were distant,but the differences between the three elements of P,Ba and Mn reached a significant level （P<0.05）;The average content of the mineral elements in egg yolk of the strain Ⅱ was higher than the others,except for Al,Cu,Pb and Si,and the difference among the three strains for the most mineral elements was reached a significant level （P<0.05）;The yolk is rich in elements such as Ca,Cu,Mn,P,Fe and Zn and the contents in egg yolk were twice higher than egg white.
