| 摘 要： | 研究了用树脂和凝胶层析法提取和精制紫红薯色素。实验结果表明：X-5树脂在吸附液pH为4．吸附流速为2.0mL／min时吸附能力较强；在室温和解吸流速为1．5mL／min的条件下．以φ=60％乙醇作为解吸剂时洗脱效果最好；采用凝胶层析法色素的色价达到49．66。

| Abstract: | The optimum conditions for purification of purple WTIpomoea batatas pigment by macroporous resin adsorption and gel filtration chromatography were studied. The result showed that the X-5 resin had greater adsorbing ability at pH =4.0 and 2.0 mL/min . When the concentration of alcohol was 65%, the desorption was the most effective at 1.5 mL/min and normal temperature. The colourity was 49.66 by gel filtration chromatography. |
