杭白菊总黄酮提取工艺的优化

Study on the optimization of extraction process of total flavonoids in chrysanthemum morifolium ramat

通过对比分析不同材料处理方法和提取方法的总黄酮得率,探索了杭白菊总黄酮的最佳提取工艺.结果表明:采用粉碎的菊花粉末,用直接回流法A1B1C1,即在提取时间为1.0 h、提取温度为80℃、乙醇体积分数为60%的条件下进行提取,可获得最高的总黄酮得率.

Using the total flavonoids production rate as an evaluation criterion,compared the methods of extracting the total flavonoids from different chrysanthemum materials,determined that the optimum extraction process was to use the direct reflux method A1B1C1 on the crushed chrysanthemum powder,namely,the ethanol concentration was 60%,the extracting temperature was 80 ℃ and the time was 1.0 h.
