摘　　要：本文研究了用201×7树脂去除萝卜红色素提取液中萝卜甙的方法。试验结果表明：201×7树脂对萝卜甙的静态交换容量最大值可达到72．gmg／ml树脂，吸附平衡时间55分钟，最适pH值5．5。用5BV0．05molNaOH溶液可完全洗脱被交换在树脂上的萝卜甙，洗脱流速1．5BV／hr。去除萝卜甙的提取液真空浓缩，喷雾干燥得粉状萝卜红色素产品，E＝4．30。A method of extracting glucoraphenin with 201 × 7 resin was studied. Adsorption capacity of 201 × 7 resin for glucoraphenin was 42. 8mg/ ml wet resin and the equilibrium time was 55 mins, and optimum PH was 5. 5. All glucoraphenin that had been adsorbed on 201 × 7 resin was eluted by 1. 5BV/hr eluent in which concentration of NaOH was 0. 05 mol/ l at the flaw rate of 1. 5BV/hr. Extracting solution of deglucoraphenin was enriched by vacuum and spray drying. A powderedproduct of Radish pigment was obtained and E = 4. 30.
