摘 要:目的开发一种利用大孔树脂富集纯化蜂胶中黄酮和酚酸类化合物的方法,并探讨其吸附过程的热力学和动力学特征。方法以芦丁为对照品,分光光度法测定总黄酮含量;以没食子酸为对照品,Folin-Ciocalteu法测定总酚酸含量。根据树脂的吸附量和解吸率,从D101、LSA-21、LSA-40、LSA-900A、LX-32、LX-60、LX-98、XDA-8G和FPA-98Cl等9种常用树脂中筛选出合适的树脂,并进行吸附热力学及动力学分析。结果FPA-98Cl树脂对蜂胶总黄酮及总酚酸的静态吸附量分别达到了80.72 mg/g和91.53 mg/g,解吸率分别为78.4%和73.4%,在上述9种树脂中吸附分离性能最好。热力学分析表明,蜂胶总黄酮在FPA-98Cl树脂上的吸附过程符合Langmuir等温线模型,蜂胶总酚酸的吸附过程符合Freundlich吸附等温线方程。动力学过程分析表明,蜂胶总黄酮在FPA-98Cl树脂上的吸附行为符合Weber-Morris颗粒内扩散方程,而Mckay准二级动力学方程更适合描述蜂胶总酚酸的吸附行为。结论大孔树脂用于富集纯化蜂胶中的黄酮和酚酸类成分是可行的,FPA-98Cl树脂是较好的选择;上述吸附热力学和动力学实验结果为后续工艺开发提供了参考。Objective To develop a novel method for the purification of the flavonoids and phenolic acids of propolis with macroporous resins,and investigate their adsorption behaviour characteristics.Methods Rutin was used as a reference for spectrophotometric determination of total flavonoids,and gallic acid was used as a reference for determination of total phenolic acids by Folin-Ciocalteu method.According to the adsorption amount and desorption rate,the best suitable resin was selected from nine usually used macroporous resins,namely,D101、LSA-21、LSA-40、LSA-900A、LX-32、LX-60、LX-98、XDA-8G and FPA-98Cl.The adsorption thermodynamics and kinetics analysis were carried out.Results For FPA-98Cl resin,the static adsorption amounts of total flavonoids and total phenolic acids were 80.72 mg/g and 91.53 mg/g,and the desorption rates were 78.4%and 73.4%,respectively.FPA-98Cl was the suitable resin for the enrichment and purification of flavonoids and phenolic acids in propolis.The adsorption process of total flavones in propolis on FPA-98Cl resin conformed to the Langmuir isotherm model,whereas the adsorption process of total phenolic acids in propolis was more consistent with the Freundlich adsorption isotherm equation.Meanwhile,the Weber-Morris intra-particle diffusion equation could describe the adsorption behaviour of total flavonoids in propolis on FPA-98Cl resin,and the Mckay quasi-second-order kinetic equation was more suitable to describe the adsorption behaviour of total phenolic acid in propolis on FPA-98Cl resin.Conclusion It is feasible to enrich and purify flavonoids and phenolics in propolis by macroporous resin,FPA-98Cl is a better choice.The experimental results of adsorption thermodynamics and kinetics provide a reference for the subsequent process development.
