| 摘 要： | 以火棘籽油为原料，采用尿素包合法对其亚油酸进行纯化，并在此基础上通过柱层析分离出鲨烯。通过单因素试验、正交试验和气相色谱-质谱联用(gas chromatography-mass spectroscopy，GC-MS)分析方法，研究尿素包合过程中包合时间、包合温度及火棘籽油、尿素和乙醇之间的配比等因素对亚油酸纯度和回收率的影响。结果表明：火棘籽油在原料:尿素:乙醇＝1:2:6(g/g/mL)、－5℃条件下包合12h，其亚油酸纯度从38.40%提高到68.55%，回收率达72.23%；纯化后的火棘籽油再经柱层析分离得到鲨烯，纯度达98.16%。

| Abstract: | In this work,urea adduction fractionation was used to purify linoleic acid from Pyracantha fortuneana seed oil and the purified product was further separated by silica column chromatography to obtain squalene.The effects of adduction time,adduction temperature and oil-urea-ethanol ratio on the purity and recovery rate of linoleic acid were probed by one-factor-at-a-time and orthogonal array design methods.The analysis of linoleic acid and squalene was performed by GC-MS.The results showed the optimal adduct... |
