摘　　要：目的 优选超声波提取番泻叶中番泻总苷的提取工艺。方法 以总番泻苷提出率为指标,采用正交试验法对总番泻苷超声提取工艺进行优选。结果 优化工艺为提取温度95℃,提取时间15 min,超声波频率40 kHz,提取前浸泡时间0 min。结论 该工艺合理,有效成分提取效率高,该法提取总番泻苷为其含量的99.1％。OBJECT To select the optimum ultrasound extraction procedure for omniseunoside from Folium Seuna. METHODS The optimum ultrasound extracting procedure was seleted with the extraction efficiency of omniseunoside from Folium Senua by orthogonal test. RESULTS The optimum ultrasound extracting procedure was: extracting temperature at 95℃, extracting time of 15 min, supersonic wave frequency at 40 kHz, with no presoke time. CONCLUSIONS It is a reasonable technique due to its high extration rate of 99. 1%.
