摘　　要： 研究了大孔树脂对芦荟叶干粉中黄酮的最佳精制工艺。在相同条件下对五种不同的大孔树脂静态吸附率和解吸率的进行测定,优选出树脂,并研究了优选树脂在不同条件下对芦荟叶干粉中黄酮的静态、动态吸附与解吸特性,确定了树脂精制芦荟叶干粉中黄酮的最佳工艺。结果表明:芦荟叶干粉黄酮精制优选大孔树脂为H1020,在室温下,吸附液pH为3.0,静态吸附能力最强,解吸剂以体积分数φ(乙醇)=80%的效果最好;动态吸附以芦荟黄酮粗提物溶液的质量浓度为12mg/mL吸附效果最好,解吸以体积分数φ(乙醇)=80%,流速为2.0mL/min洗脱效果最好。 The purification of the flavonoids from aloe leaf powder with macroporous resin was studied.The static adsorption rate and desorption rate of five different macroporous resins were surveyed under the same conditions to select the best one.The optimum purificated technic was confirmed by studying the static and dynamic absorption and desorption of flavonoids with the best resin under different conditions.The result indica-ted that the optimum macroporous resin was H1020,and its static adsorptive ability was the strongest at room temperature and pH=3,the most effective desorption could be obtained with 80% volume fraction alcohol.The best dynamic absorption was obtained at room temperature and crude flavonoids solution at 12 mg/mL,the most effective desorption was also obtained with 80% volume fraction alcohol at 2.0 mL/min desorption rate.
