摘　　要：为减少黄姜黄色素的杂质,提高其色价,就9种大孔树脂纯化黄姜黄色素进行了研究。结果表明:XDA-7吸附黄姜黄色素的能力较强,其纯化工艺为吸附和洗脱流速均为1.5mL/min,上样浓度为50mg/mL(黄姜浓度),洗脱液为60%乙醇,pH 5.0,黄姜色素得率为4.48%,色价为114.5。In order to reduce the impurities of yellow pigment from Dioscorea zingiberensis and improve its col-or value,research the purification of yellow pigment from Dioscorea zingiberensisin nine kinds of macro-porous resins.The results show macroporous resin XDA-7 is suitable to purify yellow pigment,its purifica-tion process is as follows：the flow rates of adsorption and desorption both are 1.5 mL/min,the sample con-centration is 50 mg/mL （concentration ofDioscorea zingiberensis）,the desorption solution is 60% ethanol, pH 5.0,the pigment yield is 4.48% and the color value reaches 114.5.
