To comparison and analysis the amino acid composition and content of core apricot seed kernels in Southern Xinjiang,and to screen out high quality apricot varieties. The amino acids in 29 almonds were determined by high performance liquid chromatography (HPLC). The essential amino acids of 29 varieties of apricot seeds ranged from 4.150 to 13.276 g/100 g,the total amino acids ranged from 11.840 to 42.868 g/100 g,and the SRC values ranged from 23.168 to 67.013. The principal component analysis indicated that serine and cysteine were the characteristic amino acids of apricot kernels in Southern Xinjiang. The contents of bitter amino acids,sweet amino acids,fresh amino acids and medicinal amino acids were highest in ‘Danxing’ and lowest in ‘Luntaitianrenxing’,while sour amino acids contain the highest amount of ‘Huanna’. There are 29 varieties of apricot seeds,with ‘Danxing’ having high aminoacid content and excellent quality. 
