摘要: 采用AB-8型大孔树脂对从鼠曲草中提取的总黄酮产物进行分离纯化研究。考察各种因素对树脂吸附和洗脱效果的影响。通过实验得到最佳吸附工艺条件为上样液流速2BV/h、上样液pH4.5、上样液质量浓度1.7mg/mL;最佳洗脱工艺条件为洗脱液体积分数为60%乙醇、洗脱液流速1BV/h和洗脱液用量1.8BV。分离纯化后的总黄酮产品纯度可达35.42%。

Abstract: The separation and purification of total flavonoids from Gnaphlium affine D. Don were carried out using AB-8 macroporous adsorption resin in this study. The effects of various factors on adsorption and desorption efficiency of the resin were investigated. The optimal adsorption conditions for sample loading velocity, pH value and concentration were 2 BV/h, 4.5 and 1.7 mg/mL, respectively, and the optimal desorption conditions were achieved by using 1.8 BV of 60% ethanol as desorption solvent at a flow rate of 1 BV/h. Under these conditions, the quantityof flavonoids the final product was 35.42%.
