摘要:

以静态吸附与解吸为考察指标,利用五因素四水平的正交试验对AB-8 型大孔树脂分离纯化枸骨叶总黄酮的工艺进行研究。结果表明,AB-8 型大孔树脂对枸骨叶总黄酮有较好的纯化效果,最佳纯化工艺条件为吸附液pH4.5、吸附时间4h、解吸液体积与树脂质量之比为25:1(mL/g)、解吸液为体积分数90% 的乙醇、解吸时间2.25h,在此条件下,总黄酮回收率可达90.8%,纯度为33.4%。

Abstract:

The application of AB-8 macroporous resin for the separation and purification of crude total flavonoids extract from Folium Ilicis Cornutae was evaluated in the present study. The static adsorption-desorption process of Folium Ilicis Cornutae total flavonoids on this resin was optimized using single factor and orthogonal array design methods. The results showed that a good separation and purification of crude total flavonoids extract from Folium Ilicis Cornutae was achieved using AB-8 macroporous resin. The optimum conditions for the separation and purification of crude total flavonoids extract from Folium Ilicis Cornutae were found to be: 4 h adsorption at pH 4.5 of the sample solution, followed by 2.25 h desorption using 90% ethanol as desorption solvent added at 25-fold volume of resin weight. Under these optimum conditions, the recovery of Folium Ilicis Cornutae total flavonoids reached up to 90.8% and the purity of the final product obtained was 33.4%.
