摘要
目的:对聚酰胺层析法分离纯化银杏叶总黄酮进行研究。方法通过静态吸附确定聚酰胺的最大吸附量为,动态吸附后考察不同浓度乙醇的洗脱曲线及纯度,定量采用HPLC定量测定。结果每克聚酰胺粉(已处理过)平均吸附量为:115mg;70%乙醇洗脱较合适,纯度可达到15.60%。
Objective:To study separating and purifing ginkgo flavone by Polyamide adsorption.Method:The polyamide adsorption capacity for flavone was static adsorption.Different desorption solvents were studied by dynamic adsorption,quantity analysis was carried out by HPLC.Result:Thec polyamide adsorption capacity for flavone was 115mg/g.The purify of flavone was 15.60% after being desorpt by 70% ethnol.
