摘  要:
选择12种大孔树脂,比较其对野菊花总黄酮的吸附和解吸性能。在此基础上,筛选出较优的3种大孔树脂,通过研究其静态吸附动力学特性,进一步筛选出适合分离野菊花总黄酮的理想树脂,并考察pH值和洗脱剂体积分数对其吸附容量和解吸率的影响。结果表明:XDA-1、LSA-21和AB-8树脂有较大的吸附容量和较高的解吸率,且其中XDA-1树脂显著优于另外两种,其吸附容量高达84.1mg/g、解吸率为96.2%,而且具有良好的静态吸附动力学特性,是更为适合吸附分离野菊花总黄酮的理想树脂。XDA-1树脂吸附分离野菊花总黄酮较合适的上样液pH值为4~5,洗脱剂为70%乙醇溶液。

摘  要:
Totally,12 macroporous resins were tested for their adsorption and desorption performance to total flavonoids from Chrysanthemum indicum L.,and 3 of them,namely XDA-1,LSA-21 and AB-8 resins were selected for subsequent studies,which were carried out to investigate the static adsorption and desorption behaviors of the selected resins.Finally,XDA-1 resin was selected to purify crude total flavonoid extract from Chrysanthemum indicum L.due to its higher adsorption capacity(84.1 mg/g) and desorption ratio(96.2%) and better static adsorption kinetics than those of LSA-21 and AB-8 resins.The optimum pH for XDA-1 resin adsorption ranged from 4 to 5 and the optimum desorption solvent 70% ethanol.
