摘要
为了获得较高的木荷皂甙,采用乙醇回流法对木荷提取皂甙工艺进行了优化。结果表明:影响木荷皂甙提取率的因素依次为乙醇浓度>回流温度>回流时间>pH,最佳的提取工艺是乙醇浓度60%,回流温度70℃,回流提取4h,pH 4,在该工艺条件下,木荷总皂甙提取率为0.952%。
The extraction technology of total saponins from S.superba was optimized by ethanol refluxing method to obtain higher total saponins. The results showed that the factors affecting the extraction rate of saponins were ethanol concentration ＆gt;refluxing temperature ＆gt; refluxing time ＆gt; pH. The 0.952% extraction rate of total saponins from S.superba can be obtained under the optimum condition of 60% ethanol,70℃ extraction temperature,refluxing for 4 h and pH 4.
