大孔吸附树脂分离纯化菝葜总黄酮

目的：研究大孔吸附树脂富集、纯化菝葜总黄酮的工艺条件及参数。方法：以总黄酮收率为指标,对工艺条件进行了筛选。结果：6种大孔吸附树脂和1种聚酰胺中,D140型树脂具有最佳的吸附及洗脱参数,其静态吸附容量以干树脂计为14.87 mg·g^-1。最佳吸附条件：药液质量浓度为0.5 g·mL^-1(以生药量计),吸附流速为2 BV·h^-1,吸附量为18 BV；洗脱最佳条件：以10 BV蒸馏水、5 BV的20%乙醇依次洗脱,弃去洗脱液；再用5～10 BV,60%乙醇以流速1 BV·h^-1进行洗脱,总黄酮的收率为84.72%。结论：D140型树脂综合性能较好,适于菝葜总黄酮的分离纯化。

Study on separation and purification of total flavones from Smilax china by macroporous absorption resin

OBJECTIVE: To investigate the technological parameters of the purification process of total flavones from Smilax china with macroporous absorption resin. METHOD: The technical process for purification of total flavones with the optimum macroporous absorption resin was screened by yield of total flavones product. RESULT: The D140 macroporous absorption resin had the best separating efficiency when the flavones content in the liquid was 0.5 g x mL(-1) equivalent to raw material, the volume of drug 18 BV (resin bad volume) with the adsorption-power 2 BV x h(-1), and the volume of 60% (mL x mL(-1)) ethanol as eluant 5-10 BV (resin bad volume) with desorption-power 1 BV x h(-1). The obtained flavones product has total flavones recovery rate of 84.72%. CONCLUSION: The treatment of regenerated resin is easy, this method is advisable.
