摘要
岩黑稻、岩紫糯２ 个黑米稻品种糙米的黑米色素提取率分别为 １．２％ 和１．４％ ，糠皮的黑米色素提取率分别为９．６％ 、１２．０％ ，约９０％ 的黑米色素存在于糙米糠皮中．性质研究认为，２ 品种黑米稻的黑米色素结构均属花青苷类，经组分分离鉴定，花青定３ 葡萄糖及花青定３鼠李葡萄糖可能是构成色素的组分．
In this experiment, the pigment was extracted from the 2 black rice varieties, Yanheidao and Yanzinuo, and its contents were 1.2% and 1.4% of hulled rice, respectively, but 90% in the hull.Components seperation and identification proved that black rice pigment from the 2 varieties belonged to anthocyanin consisting of Chrysanthemin and Keracyanin.
