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。
The present invention relates to extracted lipid with high levels, for example 90% to 95% by weight, oleic acid. The present invention also provides genetically modified plants, particularly oilseeds such as safflower, which can used to produce the lipid. Furthermore, provided are methods for genotyping and selecting plants which can be used to produce the lipid.
