| 摘 要： | 植物甾醇是植物中广泛存在一类具有重要生物活性物质。该文以双低油菜籽粕为原料,通过L_9(3~4)正交实验探讨从双低油菜籽粕中提取植物甾醇方法、工艺条件等。实验结果表明,在最佳条件下得率可达0.1426％(其含量为0.1531％,提取率可达93.1％)。本实验所选丙酮、石油醚、乙酸乙酯、苯、丙酮与石油醚混合物或乙酸乙酯与苯混合物等六种提取剂,除石油醚外其余提取剂对双低油菜籽粕均有良好提取效果,其中以乙酸乙酯提取效果较佳,且提取甾醇组分较全。

| Abstract: | Phytosterol is important biology active and exists in many plants. This paper explores the extraction method etc from double-low rapeseed cake. By L_9(3~4) orthogonal test, we obtained the best technological conditions of extracting. Under the optimum conditions, the yield of extraction was 0.1426% and the percent recovery of solvent was about 80%. Five solvents all can effectively extract the phytosterol. Acetic ether is the best and most of all kinds of phytosterol can extracted. |
