D 101型大孔吸附树脂对柚皮中柚皮苷的富集研究

Studies on Enrichment of Naringin from Pomelo Peel with D 101 Macroporous Adsorption Resin

目的:建立D 101型大孔吸附树脂富集纯化柚皮中柚皮苷的工艺。方法:以柚皮苷作为考察指标,对溶液的pH值、盐离子浓度、吸附时间、动态吸附因素进行研究。结果:D 101型大孔吸附树脂对柚皮苷最佳纯化工艺为溶液pH4,吸附时间1h,流速2BV·h-1,90%乙醇7BV洗脱。结论:该方法简单、可行,能够用来富集纯化柚皮中柚皮苷。

Objective： Objective： To establish a enrichment and purity process of naringin from Pomelo Peel with D 101 macroporous adsorption resin. Methods： Using naringin as standard, factors of dynamic adsorption are studied on pH of solution, concentration of salt ionic, time of being adsopted. Results： The best process of purifying naringin by D101 macroporous adsorption resin was pH 4 with solution, 1 hours of adsorption time, 2BV·h^-1 of flow rate 7BV with 90% alcohol. Conclusion： The method is simple and available , which can enrich and purify naringin from Pomelo Peel .
