| titleOfInvention | Novel phytosterol or/and phytostanol derivative preparation method |
| abstract | The present invention relates to a novel phytosterol or/and phytostanol derivative preparation method, and belongs to the technical field of food, medicine, chemical industry, cosmetics and the like. In the prior art, modification researches of phytosterol or/and phytostanol are only limited in liposolubility improvement, and an application range is limited. A purpose of the present invention is to improve water solubility of phytosterol or/and phytostanol. The preparation method comprises the following steps that: a) a certain amount of phytosterol or/and phytostanol and a polybasic organic acid or anhydride are subjected to a reaction under a catalyst effect to generate an intermediate product phytosterol or/and phytostanol polybasic acid monoester; and b) the intermediate product and a polyhydroxy compound are subjected to a reaction under a catalysis effect of a biocatalyst catalyst to generate a water-soluble phytosterol or/and phytostanol derivative, and the obtained water-soluble phytosterol or/and phytostanol derivative is subjected to column chromatography separation purification to obtain the novel phytosterol or/and phytostanol derivative. |
