摘要:

通过吸附和解吸实验筛选适合吸附分离杨桃渣多酚的大孔吸附树脂并确立纯化工艺参数。结果表明,AB-8树脂为吸附分离杨桃渣多酚物质的优良材料,较佳吸附条件为上样溶液多酚质量浓度0.9mg/mL、pH4.5、上样速率0.5mL/min;较佳洗脱条件为乙醇体积分数60%、洗脱速率0.5mL/min,在此条件下,杨桃渣多酚纯化样品多酚含量为58.82%。

Abstract:

According to adsorption and desorption performance towards polyphenols, an optimal macroporous resin was chosen from D4020, NKA-9, NKA-II and AB-8 resins for purifying crude polyphenols extracted from carambola dregs. AB-8 resin was found to have the best adsorption and desorption performance towards polyphenols and consequently, was chosen. The optimal adsorption conditions of carambola polyphenols onto AB-8 resin were determined as follows: polyphenol concentration of sample solution 0.9 mg/mL, sample pH 4.5, and feeding rate 2 BV/h, and the optimal ethanol concentration and flow rate for the desorption of carambola polyphenols were 60% and 0.5 mL/min. The content of carambola polyphenols in purified products under these conditions was 58.82%.
