该文研究在低温条件下，用乙醇作为溶剂，从大豆磷脂粉中精制磷脂酰胆碱工艺。通过单因素实验考察了提取温度、提取时间、乙醇浓度和料液比等因素在不同水平下对磷脂酰胆碱含量和得率影响。在综合考虑纯度和得率基础上，选取以乙醇（95%）为溶剂，提取温度-10℃、提取时间20 h、液料比为8∶1条件下进行中试。中试产品磷脂酰胆碱的纯度为71.74%，得率为13.48%。
該文研究在低溫條件下，用乙醇作為溶劑，從大豆燐脂粉中精製燐脂酰膽堿工藝。通過單因素實驗攷察瞭提取溫度、提取時間、乙醇濃度和料液比等因素在不同水平下對燐脂酰膽堿含量和得率影響。在綜閤攷慮純度和得率基礎上，選取以乙醇（95%）為溶劑，提取溫度-10℃、提取時間20 h、液料比為8∶1條件下進行中試。中試產品燐脂酰膽堿的純度為71.74%，得率為13.48%。

This article investigated the purification of phosphotidylcholine with alcohol solution in the condition of low temperature from soya phospholipides powder. The related factors influencing the purity and yield of phosphotidylcholine were studied through single-factor experiments. On the basis of considering the purity and yield,the conditions were selected to carry out the pilot scale experiment as follows. The concentration of alcohol is 95%,The freezing temperature is-10℃,the freezing time is 20 h and the ratio of liquor to material is 8∶1. The purity of phosphotidylcholine of pilot product is 71.74%and the yield is 13.48%.
