γ-麦胚甾醇(γ-sitosterol)是大豆甾醇的祖分之一[1],它的结构曾经从降解法测定为(I)[2,3],其中C24的绝对构型是根据氧化降解产物的分子旋光比较推定的[4-6]。我们企图从化学方法直接测定γ-麦胚甾醇的C24的绝对构型,曾经进行了一些工作。

The absolute configuration at C24 of γ-sitosterol is now established by chemical method to be 24β. The result is in contradiction to that deduced from molecular rotation comparison method but in complete agreement with that published recently and independently by Japanese workers.
