摘要: 采用柱层析法对野生越橘花色苷分离纯化进行研究。结果表明:HPD-700型大孔树脂对野生越橘花色苷的分离效果最佳,其适宜的分离条件为样品液pH2.0、花色苷质量浓度0.75mg/mL、最大上样量22BV、上样流速0.5mL/min,样品洗脱最佳乙醇体积分数60%、以流速1.5mL/min速度洗脱时、洗脱液量5BV为洗脱终点。该工艺生产的花色苷产品为紫黑色粉末,色价为62.40,回收率为86.20%。

Abstract: In this study, the separation methods of anthocyanins from wild bilberry were investigated. The results showed that the macroporous resin HPD-7 was the optimal absorption material. The optimum conditions of adsorption and desorption were pH 2.0, anthocyanins concentration of 0.75 mg/mL, sample loading volume of 22 BV (resin bed volume) the adsorption speed of 0.5 mL/min, the 60% ethanol volume as the eluent of 5 BV, and the desorption speed of 1.5 mL/min. Under the optimal separation and purification conditions, a purplish dark powder with color value of 62.40 was achieved at the recovery rate of 86.20%.
