摘　　要：河东乌麦 5 2 6、黑粒小麦 76、漯珍 1号为 3个黑粒小麦新品种 ,富含天然黑色素 ,蛋白质和 18种氨基酸以及对人体有利的各种微量元素、具有特殊的调节和保健功能。我们对这 3个黑粒小麦品种子粒色素的理化性质进行了研究。根据它们的的光谱学特性及理化特性 ,推断出黑粒小麦色素属花色苷类化合物 ,它在酸性条件下呈现红色 ,碱性条件下为兰色 ;在酸性条件下溶于水、乙醇等极性溶剂 ,为水溶性色素 ;黑粒小麦色素对光不稳定 ;随 p H值的变化表现不同的颜色 ;较耐热 (80℃ )。Black kernel wheat is a group of wheat cultivars other than red, white, purple, blue kernel color wheat. Black kernel wheat is rich in natural pigment, vitamins, protein, amino acids and beneficial trace elements, so it has special nutritious value. 3 black kernel wheat cultivars-Hedongwumai 526, Luozhen 1 and Heilixiaomai 76, were studied for their seed pigments' characters. According to their spectral and chemical characters, we concluded that the main component of seed pigment was anthocynidin, which was red in acid and blue in alkalescency. It can be solved in polar solvents such as water, ethanol. In addition, it was resistant to oxidant, stable to heat (≤80℃), easy to deteriorate under light.
