摘要: 采用硅胶薄层分离的方法,将天然红心蛋中的红色色素成分物质在硅胶薄层上分离出三条色带。进一步对三条红色带采用化学反应定性,薄层色谱,HPLC-MS-MS分析方法鉴定。结果表明三个红色带物质均为类胡萝卜素,红色物质具有与类胡萝卜素双键呈共轭状态的羰基。薄层色谱、HPLC、DAD扫描光谱、MS1及M S2鉴定结果表明三个红色带R1、R2、R3是分子量为562的紫杉红素类胡萝卜素的顺式异构体。

Abstract: The red pigments of nature red yolkin eggs were divided into three strap R1, R2 and R3 on TLC of silica gel. The components of three red straps were identified by chemical reaction on TLC, HPLC-MS-MS. The results indicated that all of the three straps R1, R2 and R3 were Carotenoids, and had conjugate keto. R1, R2 and R3 had same molecular weight 562 and were all isomers of Rhodoxanthin.
