摘要
为了研究大孔树脂静态吸附和解吸纯化苦菜多酚的工艺条件,以吸附量和解吸量为指标,从六种大孔树脂中选出最佳树脂,并研究大孔树脂静态吸附及解吸纯化的工艺条件。结果表明:NKA-Ⅱ型大孔树脂为盐碱地苦菜多酚纯化的最佳树脂。纯化的最佳条件为:吸附样液浓度2mg/mL,吸附pH为1左右,解吸液为体积分数60%的乙醇,解吸pH约为4左右。
In order to study the purification process of polyphenols from Sonchus Oleraceus by static adsorption and desorption of macroporous resin, according to the adsorption capacity and desorption performance, the best resin was screened out from six kinds of macroporous resin. And the technological conditions of static adsorption and desorption purification of macroporous resins were studied. The results showed that NKA-II macroporous resin was the best resin for purifying polyphenols. The optimum conditions for purification were determined as follows: the concentration of the sample solution 2 mg/mL, the adsorption pH about 1, the desorption solution 60% ethanol, and the desorption pH about 4.
