摘要: 以杜仲叶提取物为原料,采用酸水解的方法制备杜仲叶黄酮苷元,通过单因素及正交试验优化杜仲叶黄酮苷元的水解条件;并研究了聚酰胺两步法富集黄酮苷元的工艺条件。结果表明:当料液比为2:1(mg/mL)时,杜仲叶黄酮苷元水解的最佳工艺参数为:水解温度80 ℃,水解时间3 h,盐酸浓度6 mol/L,黄酮苷元的含量可达到2.512%。水解样品经过一次聚酰胺静态吸附,黄酮苷元的纯度可达12.87%,再经聚酰胺二次富集,杜仲黄酮苷元纯度可达63.19%。

Abstract: The preparation of flavonoid aglycone from the extract of Eucommia ulmoides Oliv.leaves was studied using acid hydrolysis.The effects of solid-liquid ratio, hydrolysis temperature,hydrolysis time and concentration of hydrochloric acid were investigated by single factor and orthogonal experiments.Based on the optimized condition,the two-step enrichment technology of flavonoid aglycones was studied.The results indicated that the optimal conditions were temperature 80 ℃,hydrolysis for 3 h,6 mol/L of hydrochloric acid,when the solidliquid ratio was 2:1 (mg/mL).Under this condition,the contents of flavonoid aglycones reached to 2.512%.The purity of flavonoid aglycones increased to 12.87% after static adsorption by polyamide resin.Finally,the purity of flavonoids glycosides can reach up to 63.19% through the twostep of enriching by polyamide resin.
