stigmasterol

the experimental results showed that with the content of water was 7 % in the azeotrope mixture, stigmasterol got the best selectivity.

结果显示二氯乙烷与正庚烷共沸系统含水7%时，豆甾醇的选择性最好。

Results: From the petrol-ether fraction of the EtOH extract of Semen Celosiae, 3 compounds were isolated and identified as β-si-tosterol ( 1), palmitic acid ( 2) and stigmasterol ( 3).

结果：从青葙子乙醇提取物的石油醚部位分离得到化合物1～3，分别鉴定为β-谷甾醇（β-sitosterol）、棕榈酸（Palmitic acid）、豆甾醇（stigmasterol）；

and the compounds of stigmasterol, ethyl gallate and butanedioic acid were obtained from this plant first time among these componds.

其中豆甾醇、没食子酸乙酯、苯甲酸为首次从该植物中分离得到。

the solubility of different phytosterols in solvent is different, so stigmasterol -enhanced phytosterol can be prepared.

各个甾醇在不同的溶剂中的溶解度有所差异，可以通过多级分步结晶的方法实现分离。

the effects of stigmasterol enrichment by different solvents

不同溶剂对豆甾醇富集效果比较
