A simple proton magnetic resonance spectroscopic method is described for the identification and and confirmation of several stereoisomeric paris of C27 stanols as well as their keto and acetate derivatives related to cholesterol. The method, which involves the use of lanthanide shift reagents, is useful in distinguishing clearly between the isomeric pairs differing only in the geometry of a functional group and/or of the A/B-ring junction in the steroid skeleton.
描述了一种简单的质子磁共振波谱方法，用于鉴定和确认几种C27甾烷醇的立体异构体对及其与胆固醇相关的酮和乙酸酯衍生物。该方法涉及使用镧系位移试剂，可有效清晰区分仅在类固醇骨架中官能团的几何形状和/或A/B环连接方式上不同的异构体对。
