Abstract:
Objective: To optimize the purification technology of saponins in steamed Panax notoginseng with macroporous resin. Methods: The main factors affecting the purification process were screened by failure mode and effects analysis (FMEA). The purification method with macroporous resin was optimized by central combination design-response surface method (CCD-RSM) based on the recovery and purity of saponins. In this experiment, the concentration of sample solution, loading volume, washing volume, ethanol concentration, and ethanol elution volume were used to investigate the purification of saponins in steamed P. notoginseng. Results: The optimized purification process with macroporous resin was as follows: maximum recovery (82.81%) and purity (77.24%) of saponins were obtained with the concentration of saponin solution of 11.22 mg/mL, loading volume of 4.97 BV, washing volume of 2 BV, ethanol concentration of 70%, and ethanol elution volume of 3.31 BV. Conclusion: The optimized purification process based on FMEA and CCD-RSM is convenient and stable, with high recovery and purity of saponins, which has a certain practical value.
