摘要
本文采用萃取法和重结晶法对红木种子中的红木色素进行了分离和纯化,利用分光光度法对油溶性的红木素产品进行了定量分析,并借助UV、FTIR、MS、1HNMR及13CNMR等测试手段对红木素的组成和结构进行了表征。
In this paper, the methods of solvent extraction and re-crystallization were used to separate and purify red pigment from annatto seeds. The pure red pigrnent-bixin was obtained and quantified by 721 type spectmphotometer. The composition and structure of the bixin were characterized by IR、UV、MS、^1H NMR and ^13C NMR.
