| Abstract: |
| [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. |
