新疆南疆杏核心种质种仁氨基酸比较分析

Comparison and analysis of amino acids in kernel of apricot core germplasm in Southern Xinjiang

采用高效液相色谱法测定新疆南疆29个杏品种的种仁氨基酸组分与含量,筛选出品质好的仁用杏品种。结果显示:新疆南疆29个杏品种的种仁中必需氨基酸含量为4.150~13.276 g/100 g,总氨基酸量含量11.840~42.868 g/100 g,其比值系数分(SRC值)为23.168~67.013;主成分分析表明丝氨酸、半胱氨酸为南疆杏种仁的特征性氨基酸。苦味氨基酸、甜味氨基酸、鲜味氨基酸及药用氨基酸含量,均以‘旦杏’含量最高,‘轮台甜仁杏’含量最低;而酸味氨基酸含量以‘胡安娜’最高;在29个杏品种中,‘旦杏’种仁氨基酸含量高,品质优良。

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 amino acid content and excellent quality.
