摘要：目的：研究超声提取方法对三七中皂苷的提取率的影响。方法：采用高效液相色谱(HPLC)法比较不同超声提取时间与常规浸泡对三七皂苷的提取率。结果：三七中皂苷的提取率随超声提取时间的增加而增加，在30 min～8 h的时间范围内差异不显著，和常规浸泡相比，超声提取缩短提取时间数十倍，提取率略高于常规浸泡，但也无显著差异。结论：超声法提取三七皂苷能显著提高提取效率，采用超声提取30 min～1 h可以代替常规浸泡36 h处理的方法。关键词：三七；皂苷；超声提取；高效液相色谱

Abstract:Objective:To Study on ultrasonic extracting how to affect the rate of extraction in saponins of Panax notogineng.Methods:The contents of saponins were determined by HPLC.Results:The time of ultrasonic extracting is shortened many multiples than the common extracting, either of rate of extraction are not obvious differente.Conclusion:To choose the 30 min～1 h of ultrasonic extracting replace the 36 h of common extracting.
