泡沫分离法纯化无患子皂苷

Purification of sapindus-saponin by foam separation

目的:采用泡沫分离法分离无患子皂苷,得到其分离纯化的最佳条件。方法:利用正交实验的方法分析实验结果,优化泡沫分离的工艺条件。结果:当原始料液浓度2.5 g/L、气体流速0.9 L/min、温度30℃、pH值4.8时,无患子皂苷的收率为69.42%,富集比为2.48,纯度达67.78%。结论:泡沫分离法分离无患子皂苷工艺简单,产品收率高,为天然无患子皂苷的开发利用提供了基础。

AIM： To adopt the foam separation to get the best condition of the process about separation-purification sapindus-saponin. METHODS： The orthogonal experiments was used to analyse the results of the process. RESULTS ： The best condition of the process was 2.5 g/L feed concentration, 0.9 L/min gas flow rate, pH 4.8 and the temperature of 30℃. Under this condition, the yield, concentration ratio and purity of sapindus-saponin was 69.42%, 2.48, and 67.78%, respectively. CONCLUSION： The process is very simple and practical, which provides a base for the application of natural sapindus-saponin.
