目的] 考察赤芍提取物目的大孔树脂纯化工艺.方法] 以芍药苷为指标,进行了树脂型号目的选择,考察了上样量、洗脱溶剂目的浓度及用量、树脂重复使用次数、再生后吸附力目的恢复等.结果] 选择D101大孔树脂,上样量为树脂体积:生药=1:1g(v/w),洗脱溶剂4倍量为70%乙醇.结论] 工艺经济简单实用,可以应用于纯化赤芍提取物.

Study on the purification technology of radix paeoniae rubra extract by macroporous rresin

Objective] To study the purification technology of Radix Paeoniae Rubra extract by macroporous resin.Methods] Taking peoniflorin as the index constituent, the type of resin was chosen. The sampling amount and elution solvent were decided and the times for repeated use and recovery capacity after regeneration were studied.Results] D101 was chosen for purification, the suitable sampling ratio of resin volume to raw material was 1:1. The elution solvent was 4-fold 70% ethanol.Conclusion] The technology is economic, simple and practical and can be used to purify Radix Paeoniae Rubra extract.
