摘要
以弱碱性阴离子交换树脂D301吸附水溶性红曲色素溶液,95%乙醇洗脱,然后进行HPLC分析,结果表明,红曲色素含有8种黄色素组份,其最大吸收峰均在380 nm附近;弱碱性阴离子交换树脂D301可实现红色素与黄色素组份的有效分离.
Solution of water-soluble Monascus dye was adsorbed by D301 anion exchange resin and eluted by 95% （v/v） ethanol-water. The elate and mother liquor were detected via HPLC （high-performance liq uid chromatography）. The results showed that Monascus dye contained 8 kinds of yellow dye, whose char acteristie absorption peak was about 380nm and that the red dye and yellow dye could be separated effec tively by D301 anion exchange resin.
