摘　　要：采用大孔吸附树脂法分离纯化肉桂总黄酮,考察影响树脂静态和动态吸附与洗脱主要因素,确定肉桂总黄酮分离纯化优化工艺条件。结果表明:HPD-500大孔吸附树脂分离纯化效果较好,其对肉桂总黄酮静态吸附和解吸最佳工艺条件为吸附平衡时间6h、解吸平衡时间2h、样液质量浓度0.8mg/mL、样液pH6.0、洗脱剂乙醇体积分数80%;其对肉桂总黄酮动态吸附和洗脱最佳工艺条件为上样液质量浓度1.2mg/mL、上样液流速1.5mL/min、洗脱剂流速2.0mL/min、洗脱剂(80%乙醇)体积45mL时洗脱完全。在此条件下,分离纯化得到总黄酮含量为91.81%。The purification of total flavonoids from cinnamon was studied using macroreticular resin. Critical process variables that influence the static and dynamic adsorption and desorption of total flavonoids were selected and optimized. HPD-500 type macroreticular resin was found to be optimal for purifying total flavonoids from cinnamon. The optimal experimental conditions for static adsorption and desorption were determined as 6 h, 2 h, 0.8 mg/mL, 6.0 and 80% ethanol for adsorption time, desorption time, sample concentration, sample pH and desorption solvent, respectively. The optimal experimental conditions for dynamic adsorption and desorption were loading of 1.2 mg/mL sample solution at pH 6.0 with a flow rate of 1.5 mL/min and complete desorption with 45 mL of 80% ethanol at a flow rate of 2.0 mL/min. The content of total flavonoids in purified products under the optimized conditions was 91.81%.
