Abstract: Adult nourishment component of Epicauta chinensis was determined in this research, in total it contains 7 kinds of trace elements,and Zn and Fe reached 0.038 28% and 0.041 47% respectively in experimentation sample. The proportion of unsaturated fatty acid(P) and saturated fatty acid(S) is 2.78,the content of C_(18:2) and C_(18:3) in fatty acid is the 28.5% and 36.2% respectively, the content of amino acid in experimentation sample is 50.15%,the content of Glu is the highest,reached 7.19%. Analysed result showed that E. chinensis contained high protein,low fat and abundant trace elements.
