摘要

摘要研究了6种树脂(HP-20、AB-8、X-5、DM130、HPD100、D4006)对山楂黄酮的吸附解吸性能。筛选出的HP-20树脂吸附量最佳，吸附量为24.2 mg/g。采用Langmuir和Freundlich等温模型、拟一阶和拟二阶动力学模型和颗粒内扩散模型拟合吸附过程。结果表明，HP-20对山楂黄酮的吸附过程符合Langmuir等温模型和拟二阶模型，最佳吸附温度为298 K。热力学参数表明，吸附过程是自发放热的。纯化后的山楂黄酮具有较高的乙酰胆碱酯酶抑制活性。

Adsorption and desorption characteristics of flavonoids extracted from hawthorn (Crataegus pinnatifida) on macroporous resin

Abstract In this work, the adsorption and desorption capacities of six resins (HP-20, AB-8, X-5, DM130, HPD100, D4006) for the purification of hawthorn flavonoids were investigated. HP-20 resin was screened out that has the best adsorption capacity, with an adsorption capacity of 24.2 mg/g. Langmuir and Freundlich isotherm model, pseudo first-order and pseudo second-order kinetics and intra particle diffusion model were used to fit the adsorption process. The results indicated that the adsorption process of hawthorn flavonoids by HP-20 was in accordance with the Langmuir isotherm model and pseudo second-order model, and the optimal adsorption temperature was 298 K. The adsorption process was spontaneously exothermic as indicated by thermodynamic parameters. After purification, hawthorn flavonoids showed high acetylcholinesterase inhibitory activities.
