Beschreibung
Zusammenfassung:	The invention discloses a method for preparing cholesterol and derivatives thereof by taking phytosterol as a raw material. The preparation method comprises the following steps: taking phytosterol asa starting raw material, carrying out etherification protection on 3-hydroxyl of the phytosterol, and carrying out biological fermentation, oxidation, GM-2 oxidation, witting reaction, hydrogenation and hydrolysis to obtain cholesterol and derivatives thereof. According to the invention, sterols are developed and utilized, so that the problem of raw material sources is solved, and the environmental protection problem of waste water and waste residues is also solved. 本发明公开一种以植物甾醇为原料制备胆固醇及其衍生物的方法。包括如下步骤：以植物甾醇为起始原料，对植物甾醇的3位羟基进行醚化保护，经生物发酵、氧化、GM-2氧化、witting反应、氢化、水解得到胆固醇及其衍生物。本发明对这些甾醇进行开发利用，不仅解决了原料来源问题，更是解决了废水废渣的环保问题。
