天然红心鸭蛋中红色素的化学及光谱性质研究

The Chemistry and Spectrum Character of Red Pigment of Nature Duck Eggs Red Yolk

采用薄层、化学反应、紫外-可见和红外光谱的方法,分析了天然红心鸭蛋中的红色色素性质。结果表明天然红心鸭蛋中红色色素为类胡萝卜素,该红色类胡萝卜素不含羟基,具有与类胡萝卜素双键呈共轭状态的羰基。

The paper probed into the chemistry and spectrum character of red pigment of nature duck eggs red yolk by TLCof silica gel., chemical reaction, UV-VIS, IR spectrum. The results indicated that the red pigment of natural red yolk isCarotenoids, and had conjugated keto, no hydroxyl.
