目的考察大孔树脂对过岗龙多酚的吸附性能和较优的纯化工艺参数,确立纯化过岗龙多酚的较优工艺。方法以过岗龙多酚的吸附量和解吸率为指标,考察纯化过岗龙多酚的最佳吸附树脂,并确立其工艺参数。结果 AB-8大孔树脂的吸附解吸性能最佳,其纯化过岗龙多酚的最佳工艺为:提取液上样液浓度为2.65 mg/ml,上样量12 BV,p H值为3.0,上样流速为7 BV/h,洗脱剂为5 BV的70%乙醇,洗脱流速3 BV/h。结论在该条件下,过岗龙总多酚纯度由纯化前的23.49%提高到47.38%,说明AB-8大孔树脂对过岗龙多酚的纯化具有显著的作用。研究结果为过岗龙多酚的进一步开发利用提供了依据。
Objective To investigate the adsorption of macroporous resin on polyphenols and optimize the purification process parameters to establish a better process for purifying polyphenols. Methods The adsorption capacity and desorption rate of polyphenols of perphenocarp were used as indexes to investigate the optimum adsorption resin of polyphenols for purifying polyphenols and establish the process parameters. Results The best adsorption and desorption properties of AB-8 macroporous resin were as follows: the concentration of extract solution was 2.65 mg / ml, the sample volume was 12 BV and the value of p H was 3.0 , A sample flow rate of 7 BV / h, an eluent of 5 BV of 70% ethanol, and an elution flow rate of 3 BV / h. Conclusions Under this condition, the purity of total polyphenols in Toramenosaurus increased from 23.49% to 47.38% before purification, indicating that AB-8 macroporous resin has a significant effect on the purification of TOL. The results provide the basis for the further development and utilization of polyphenols.
