Separation of Δ5- and Δ7-Phytosterols by Adsorption Chromatography and Semipreparative Reversed Phase High-Performance Liquid Chromatography for Quantitative Analysis of Phytosterols in Foods
A method for the separation, isolation, and identification of phytosterols was developed. A commercial phytosterols mixture, Generol 95S, was fractionated first by adsorption silica gel column chromatography and then separated by means of a semipreparative reversephasehigh-performanceliquidchromatography fitted with a Polaris C8-A column (250 mm x 10 mm i.d., 5 microm) using isocratic acetonit
开发了一种分离,分离和鉴定植物甾醇的方法。首先通过吸附硅胶柱色谱法分离市售的植物甾醇混合物Generol 95S,然后通过装有Polaris C8-A色谱柱(250 mm x 10 mm内径,5微米)的半制备反相高效液相色谱法进行分离。 ),使用等度乙腈:2-丙醇:水(2:1:1,v / v / v)作为流动相。获得了六种单独的植物甾醇的毫克级,其中包括香茅甾烯醇,菜油甾醇,β-谷甾醇,Delta7-菜甾醇,Delta7-菜甾醇和Delta7-谷甾醇。这些分离的甾醇的纯度为85-98%。计算这些植物甾醇相对于胆固醇的相对响应因子(RRF)作为真实的商业标准。
