为了探讨乌桕籽粗脂肪提取的最佳工艺条件，以河池学院校园内采集的乌桕籽为实验材料，通过单因素试验、正交试验，考查了溶剂种类及所选溶剂的浓度梯度、提取时间、提取温度和料液比对乌桕籽粗脂肪提取率的影响，通过验证性试验确定乌桕籽粗脂肪提取的最佳工艺条件。结果表明，乌桕籽粗脂肪提取的最佳工艺条件为：选用无水乙醇作为提取剂，提取时间120 min，提取温度100℃，料液比1∶25（g／mL）。此条件下，乌桕籽粗脂肪的平均得率为43．28％。该工艺条件稳定，重复性好。%In order to study the optimal crude fat extraction conditions of Sapium sebiferum seeds, the experi-mental sample was collected on Hechi university campus .By single-factor test and orthogonal test , the effects of different kinds of solvent , concentration gradient of the chosen solvent , extraction time , temperature and solvent ra-tio on extraction rate of S.sebiferum seeds crude fat were examined .By confirmatory test , the optimum extraction process conditions of S.sebiferum seeds crude fat were confirmed .The results show that the optimal extraction sol-vent, time, temperature, sample-solvent ratio is anhydrous ethanol , 120 min, 100℃, 1∶25 g/mL, respectively. Under this condition , the average production rate of crude fat reaches 43 .28%.The process condition is stable and with good repeatability .
