摘　　要：研究南阳彩色小麦中氨基酸的含量水平,为该小麦系列新品种的开发利用提供科学依据,以南阳灰色、蓝色、紫色小麦为原料,以河南几种豫麦品种为对照,用高效液相色谱法对其氨基酸组成和营养品质进行了初步分析。实验结果表明:南阳彩色小麦的氨基酸含量较高,质量分数依次为普通紫色小麦15.88%,硬质紫色小麦15.63%,蓝色小麦14.84%,灰色小麦为14.35%。小麦蛋白质中氨基酸的种类齐全,紫色小麦中苏氨酸的含量较普通小麦增幅115.15%。8种必需氨基酸比例合适,组成合理,其中酪氨酸和苯丙氨酸的比例较高。经综合分析,紫色上麦的营养价值较高,建议做进一步的开发研究。We use Nanyang color wheat as raw materials, and use the Henan good quality wheat to compare with the common wheat. Amino acid in 9 varieties of wheat were studied by high performance liquid chromatography, The results showed that amino acid in color wheat was higher than that in common wheat, about 15.88 % in common violet wheat~ 15.63 % in hardness violet wheat, 14.84 % in blue wheat and 14.35 % in grey wheat. The threonine in violet wheat was 115.15% higher than it in common wheat. The balance analysis of the necessary amino acid showd that the contents of leucine and tyrosine ＋ phenylalanine in accord with the standard demands of FAO and WHO, the contents of the other six necessary amino acid do not achieve the standard. The proportion of 8 necessary amino acid is suitable for people. The seed protein from wheat grain is the richest in violet wheat. We suggest that it needs to have a deeply exploitation.
