摘要
目的研究8种不同类型吸附树脂对柿叶黄酮的吸附特性。方法测试它们对柿叶黄酮的吸附率、吸附速率、解吸率和产物得率及其黄酮含量。结果发现聚酰胺和AB8树脂对柿叶黄酮吸附量大,吸附快、解吸容易,吸附后产物黄酮含量高。结论聚酰胺和AB8树脂是一种性能良好的柿叶黄酮吸附剂,可用于从柿叶提取物中富集制备含量达70%以上的柿叶黄酮,为柿叶黄酮的开发提供新工艺。
AIM: To screen macroreticular resins for isolation and purification of flavonoids from the leaves of Diospyros kaki Linn (FLDK). METHODS: 8 kinds of macroreticular resins were assayed for their adsorbability and deadsorbability as well as the adsorption kinetics to FLDK. RESULTS: Polyamide and AB-8 resin were found with good adsorbability and deadsorbability as well as adsorption kinetics to FLDK. CONCLUSION: AB-8 resin and polyamide could be used for preparing high contents of FLDK. FLDK-P70, a flavonoid extract contained more than 77% of flavonoids was prepared from the extract of leaves of Diospyros kaki by polyamide adsorption column isolation.
