大孔树脂对甘草渣总黄酮吸附分离特性及工艺研究

Absorption and desorption behaviour of the total flavones from Glycyrrhiza residues on macroporous adsorption resins

  • 摘要: 探讨了大孔吸附树脂富集甘草渣中总黄酮的吸附分离特性并确定纯化工艺。通过对5种树脂进行静态吸附解吸实验,筛选出适宜的大孔树脂(AB-8和SP825)对其热力学、动力学特性进行考察,并优化分离纯化工艺条件。动力学研究表明,拟二级动力学模型能很好的描述2种大孔树脂(AB-8和SP825)的整个吸附过程。热力学研究表明,2种树脂对甘草渣总黄酮的吸附符合Freundlich等温吸附方程,吸附过程是放热的,而且是物理吸附的过程。AB-8大孔树脂对甘草渣总黄酮的最佳分离纯化工艺为:甘草渣提取液上样浓度1.089 mg/m L,上样体积2 BV,上样流速3 m L/min,之后用3 BV 80%乙醇洗脱,洗脱流速1.5 m L/min,此时解吸率达91.67%,此条件纯化后总黄酮的纯度提高到53.43%。AB-8大孔树脂用于甘草渣总黄酮的纯化效果最佳。 

     

    Abstract: The adsorption and desorption behaviours of macroporous resins for enriching total flavonoids from Glycyrrhiza residues were investigated.Five macroporous resins were studied using the static adsorption method.Additionally two representative resins( AB-8 and SP825) were chosen for adsorption thermodynamics and kinetics model studies,the conditions for purifying were optimized. The kinetics results showed that the whole adsorption process can be described better by the pseudo-second order kinetics model.The thermodynamics results showed that the adsorption process fited the Freundlich isothermal model,the adsorption of the representative resins was an exothermic and physical adsorption process. The optimum process conditions for purifying the total flavonoids from Glycyrrhiza residues using AB-8 resin were determined as follows: sample concentration of 1.089 mg / m L,flow velocity of 3 m L / min,sample volume of 2 BV,and amount of 80% ethanol as desorption solvent 3 BV,flow velocity of 1.5 m L / min. By this time the desorption rate was 91.67%. The purity was increased to 53.43%,which showed that AB-8 macroporou resin had better adsorption property. It can be used to purify and separate total flavonoids from Glycyrrhiza residues.
