摘　　要：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/m L)。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 experimental 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 tio on extraction rate of S. sebiferum seeds crude fat were examined. , extraction time, temperature and solvent ra- 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.
