摘　　要：为优化零陵香总黄酮提取工艺,本文在单因素试验基础上,依据Box-Bebnken的方法设计对乙醇体积分数、微波时间、微波功率和液料比四因素进行优化。结果表明:零陵香总黄酮的最佳提取工艺为乙醇体积分数75%,微波时间17 min,微波功率600 W,液料比68 mL/g。本试验得到的工艺条件参数可行性强,重复性好,为提高零陵香的开发利用提供一定的参考依据。In order to optimize the extraction process of total flavonoids from Linglingxiang,based on the single factor experiment and box bebnken method,the four factors including ethanol volume fraction,microwave time,microwave power and liquid-solid ratio were designed.The results showed that the optimum extraction conditions were ethanol volume fraction 75%,microwave time 17 min,microwave power 600 W,liquid-solid ratio 68 mL/g.The pararmeters obtained in this experiment have strong feasibility and good repeatavility,which provided a certain reference for the development and utilization of Linglingxiang.
