摘　　要：以超声时间、提取温度、乙醇浓度和固液比为因素,每因素进行3水平的正交实验,用紫外分光光度法测定中药制剂——促生长散中厚朴酚的含量和以其作为综合评价指标。结果发现提取实验中影响因素最大的是乙醇浓度,最佳提取条件为:超声时间60(20,20,20)min,超声温度35℃,乙醇浓度65%,固液比1:10。The best condition of ethanol extraction of Magnolol from drug" herbal medicine of promoted growth" assisted by ultrasonic wave was studied in this paper. The orthogonal design showed that the best ultrasound time, temperature, ethanol concentration and solid-liquid ratio were 60 min( three times and 20 min per time), 35℃, 65% and 1:10, respectively. Moreover, ethanol concentration was shown to be the most important influential factor among the investigated factors.
