【摘要】 从10种大孔吸附树脂中筛选出D101树脂,并研究其对燕麦麸皮多酚静态与动态的吸附及解析性能。试验表明,D101树脂对燕麦麸皮多酚的静态饱和吸附量为64.01 mg/g(干树脂),饱和吸附时间为5 h,解吸剂乙醇溶液的适宜体积分数70%。以质量浓度为3.046 mg/mL,流速为1.0 mg/min燕麦麸皮提取液上柱时,树脂的多酚穿透吸附容量63.28 mg/g(干树脂),60 mL体积分数70%的乙醇溶液可将吸附于柱上的燕麦麸皮多酚基本完全洗脱。结果显示,D101树脂的吸附和解析性能较好,适合于燕麦麸皮多酚的纯化。更多还原

【Abstract】 D101 resin is selected from 10 kinds of macroporous adsorbent resins and its performances in adsorbing and desorbing of polyphenols from oat bran is studied.The results show that the static saturation adsorption capacity of D101 resin is 64.01 mg/g dry resin,and it takes 5 h to achieve saturation adsorption.70%volume fraction ethanol is the optimal elutant for the elution of polyphenols adsorbed on the resin.The breakthrough adsorption capacity of the resin is 63.28 mg/g dry resin at a feeding concentration of 3.046 mg/mL and a flow rate of 1.0 mg/min.60 mL of 70%volume fraction ethanol can completely elute the oat bran polyphenols adsorbed on the column.D101 resin processes higher adsorption and desorption capacity,thus is suitable for the purification of oat bran polyphenols.更多还原
