摘要: 分别采用单因素试验法和正交试验法对水浴和超声波辅助回流提取法对百合总皂苷的提取工艺进行比较,获得最佳水浴回流提取工艺为:乙醇浓度为50%、温度为90 ℃、提取时间为3 h、固液比为1:18。在该工艺条件下百合皂苷的提取率为1.98%;超声波辅助回流提取最佳工艺为:温度为90 ℃、乙醇浓度为70%、提取时间为25 min、固液比为1:30、提取功率为105 W。在该工艺条件下百合皂苷的提取率为2.33%,超声波辅助回流提取法的百合皂苷提取率和稳定性、重复性都优于传统的水浴回流提取法。

Abstract: In this study,single factor and orthogonal tests were carried out for the optimization of water bath reflux extraction and ultrasonic-assisted reflux extraction of saponins from Lilium brownii separately.The optimal water bath reflux extraction conditions were:50% ethanol as extraction solvent,90 oC as extraction temperature,3 h as extraction time and 1:18 as solid-liquid ratio.Under these conditions,the extraction yield of saponins from L.brownii was 1.98%.The optimal ultrasonic-assisted reflux extraction conditions were:70% ethanol as extraction solvent,90 oC as extraction temperature,25 min as extraction time,1:30 as solidliquid ratio and 105 W as ultrasonic power.Under these conditions,the extraction yield of saponins from L.brownii was 2.33%.Compared with traditional water bath reflux extraction method,the stability,repeatability as well as the extraction yield of ultrasonic-assisted reflux extraction was better.

Key words: Lilium brownii, saponins, reflux extraction, ultrasonic-assisted reflux extraction, extraction process
