摘要:

目的:研究D-101 大孔吸附树脂分离纯化橘皮黄酮类物质的工艺条件。方法:采用静态和动态吸附- 解吸附两种方法,以黄酮类物质吸附率和解吸附率为评价指标,考察橘皮提取液pH 值、吸附液料比、静置吸附时间、洗脱液种类和洗脱液料比等影响因素。结果:D-101 大孔吸附树脂分离纯化橘皮黄酮类物质的最佳工艺条件为提取液pH4.43,吸附液料比15:1(黄酮类物质溶液:大孔吸附树脂,mL/g)、静置吸附时间90min、洗脱液为95%乙醇溶液、洗脱液料比25:1(95% 乙醇溶液:大孔吸附树脂,mL/g)。结论:该方法简单、可行,能够用来分离纯化橘皮中黄酮类物质。

Abstract:

To propose an optimal purification process of total flavonoids in 70% ethanol extract from citrus peel, the static and dynamic adsorption-desorption performance of D-101 macroporous adsorption resin towards total flavonoids from citrus peel was investigated. Major process parameters including pH of sample solution (ethanol extract of citrus peel), sample solution volume/D-101 resin weight ratio (mL/g), standing time and kind and amount (desorption solvent volume/ D-101 resin weight ratio, mL/g) of desorption solvent affecting either adsorption ratio or desorption ratio of total flavonoids were evaluated and their optimal values were determined to be pH 4.43, 15:1, 90 min, 95% ethanol and 25:1, respectively. The method proved to be simple and feasible for purification of crude total flavonoids extracted from citrus peel.

Key words: citrus peel, total flavonoids, D-101 macroporous adsorption resin, static adsorption, dynamic adsorption
