大孔树脂分离纯化商陆红色素的研究

Investigation on Isolation and Purifying of Phytolacca Americana Red Pigment with D301 Ion Exchange Resin

研究了几种大孔吸附树脂和离子交换树脂对商陆红色素的静态吸附特性,筛选出一种吸附性能较好的树脂,并应用柱层析进行商陆红色素的分离纯化研究。实验结果表明:D301离子交换树脂对商陆红色素的静态吸附率达到96.0%,柱层析吸附饱和后用0.15 mol/L HCl洗脱时,洗脱率达到92.8%,洗脱液经低温干燥得到的商陆红色素色价达到45.9。

The absorption character of phytolacca americana red pigment was studied by several absorption resin and ion exchange resin, then the D301 ion exchange resin is selected to isolating and purifying Phytolacca Americana Red pigment in this paper. Experiments show： the absorption rate of D301 is 96.0 %, when absorption is full, use 0.15 mol/L HCl washout,The washout rate of 0.16mol/L HCl is 92.8%.
