摘 要:目的:建立大孔树脂同时分离纯化淫羊藿中淫羊藿苷和淫羊藿次苷Ⅱ的工艺条件。方法:以淫羊藿苷和淫羊藿次苷Ⅱ的吸附容量、洗脱率为评价指标,通过静态吸附-洗脱试验筛选大孔树脂型号,采用单因素试验优选淫羊藿苷和淫羊藿次苷Ⅱ的吸附和洗脱条件。结果:选用DM301型大孔吸附树脂,最佳吸附条件为上样液质量浓度7.45 g·L-1,上样液流速3BV·h-1;淫羊藿苷洗脱条件为加45%乙醇4 BV以1.5 BV·h-1的流速进行洗脱;淫羊藿次苷Ⅱ洗脱条件为加60%乙醇5 BV以1.5 BV·h-1的流速进行洗脱;淫羊藿苷、淫羊藿次苷Ⅱ纯度分别达56.23%,67.41%。结论:建立的工艺条件可同时分离纯化淫羊藿苷和淫羊藿次苷Ⅱ,且稳定性好、收率较高、生产成本低,适宜于规模化生产推广。Objective: To optimize separation and purification technology of icariin and icariside Ⅱ from Epimedii Folium by macroporous adsorption resin. Method: Taking adsorption capacity and desorption rate of icariin and icariside Ⅱ as indexes,macroporous resin models were screened by static adsorption-elution test,single factor tests were adopted to investigate adsorption and elution conditions. Result: DM301 macroporous resin was the most suitable one for purification of icariin and icariside Ⅱ,its optimum adsorption conditions were as follows:the concentration of sample solution 7.45 g·L-1,sample flow rate 3 BV·h-1;Elution conditions of icariin was eluting with 4 BV 45% ethanol at 1.5 BV·h-1;Elution conditions of icatiside Ⅱ was eluting with 5 BV 60% ethanol at 1.5 BV·h-1;Under these conditions,purities of icariin and icariside Ⅱ were 56.23% and 67.41%,respectively. Conclusion: These established process conditions could be adopted to separate and purify icariin and icariside Ⅱ at the same time with good stability,high yield and low production cost,which were suitable for industrial production.
