摘要:

以黑果腺肋花楸为原料,采用大孔树脂纯化黑果腺肋花楸中多酚类物质。通过对比6 种大孔树脂对黑果腺肋花楸多酚吸附-解吸效果,筛选出XAD-7大孔树脂作为最佳纯化材料,并通过单因素试验确定XAD-7大孔树脂纯化黑果腺肋花楸多酚的静态吸附-解吸最佳工艺条件为:吸附时间4 h、解吸时间2 h、上样液质量浓度3.6 mg/mL、上样液pH 4、乙醇体积分数95%、乙醇溶液pH 7;其对黑果腺肋花楸多酚动态吸附-解吸最佳工艺条件为:上样流速2 mL/min、上样量560 mL、蒸馏水洗脱用量350 mL、洗脱流速2 mL/min、洗脱体积300 mL。在此条件下,黑果腺肋花楸多酚纯度由11.62%提高到64.37%,表明XAD-7大孔树脂对于黑果腺肋花楸多酚具有较好的纯化效果。

Abstract:

In this study, six different macroporous adsorption resins were evaluated for their use to purify polyphenols from
Aronia melanocarpa berries. Macroporous resin XAD-7 was selected as the most suitable one. The purification parameters
optimized by static adsorption and desorption tests were as follows: adsorption and desorption time, 4 and 2 h, respectively;
sample concentration, 3.6 mg/mL; sample pH, 4; and desorption solvent, 95% ethanol (pH 7). The best purification
parameters optimized by dynamic adsorption and desorption tests were as follows: sample loading amount, 560 mL; flow
rate, 2 mL/min; washing the column with 350 mL of water; and subsequent elution with an eluent volume of 300 mL at
2 mL/min flow rate. Under these conditions, the purity of polyphenols from A. melanocarpa was improved from 11.62% to
64.37%, indicating that macroporous resin XAD-7 has a better effect in purifying polyphenols from A. melancarpa.
