大孔吸附树脂用于赤芍总甙分离方法的探索

目的：研究用大孔吸附树脂分离赤芍总甙。方法：赤芍以７０％的乙醇回流提取、减压浓缩，过大孔吸附树脂柱，分别用水、２０％乙醇洗掊，收集２０％乙醇洗脱液，减压浓缩得赤芍总甙。结果：收率为５．４％，其中芍药甙的含量占赤芍总甙的７５％。结论：得率高且稳定可控。

Studies on Separation of Total Saponin of Paeonia by Macro Absorption Resin

Objective: To study the separation of total saponin of Paeonia by macro absorption resin.Methods: The root of paeonia lactiflora Pall or Paeonia veilchii Lynch are extracted with 70% ethanol under reflux, concentracted under reduced pressure, eluated on macro reticular absorption resin column using water and 20% ethanol as eluation, respectively, then the 20% ethanol eluation was collacted and concentrated under reduced pressure.Results: The yield was 5.4%, the paeoniflorin content in 75% of total saponin of Paeonia.Conclusion: By the method, extraction rate is high, and process is stable and controllable.
