摘要
对超声波提取杜仲叶中的活性成分工艺进行了研究,并与常规加热回流法进行比较分析。结果认为,超声波提取的最佳条件为:提取前的浸泡时间是60～90min,提取时间为40min,超声波频率为40kHz;超声波提取对热敏性物质的提取效果优于加热回流法。
Extraction technics of metabolites in Eucommia ulmoides leaves by ultrasonic were studied. Ultrasonic and heating method were compared. The results were as follows: the optimum condition was pre-marinate the material 60～90 min, and then extracted 40 min with the ultrasonic waves under 40 kHz. The ultrasonic wave was better than heating method on the extraction of instability metabolites.
