采用超声波技术提取苦参中的生物碱成分，在单因素试验的基础上，通过正交试验和方差分析，确定最佳提取工艺条件为：料液比1∶10，浸泡时间3 h，乙醇浓度80%，提取时间20 min。超声波提取苦参总生物碱具有省时、提高提取率、降低成本等优点，结果表明，加入苦参碱的提取率由0.213%提高到0.472%。
The experiment has used ultrasonic technology to extract the alkaloid composition from Sophara flavescens Ait.On the basis of singel factor experiment,an orthogonal experiment and analysis of variance are carried out.So the optimum extraction conditions contain of the ratio of solid to liquid(1∶10),time of soak(3h),ethanol(80%),and time of extraction(20min).Campared to the traditional cooking method,extracing the alkaloid composition in ultrasonic wave has advantages in saving time,eanhancing drawing rate and cutting costs.The result shows that it rises to 0.472% from 0.213% to join the extraction rate of matrine.
