Objective: AccQ- Tag methods used in this paper, derivatized with 6- arninoquinolyl- N- hydroxysuccinimidyl carbauiate (AQC) as the reagent, isolated and tested samples of black barley types and levels of free amino acids. The results show that: in the detection of nine free amino acids, the lowest was Asp(2.3±0. 031μmol/g), and the highest was phe(347.6 ±8. 052μmol/g) which is 46.67% of total amino acids, And the amino acid concentration and peak area showed a good linear relationship between higher stability; This method is simple, accurate and reliable, high sensitivity, it can be used prospectly in the development and use and quality control of the black Barley.
