A method of resolving a racemic mixture of (±)-Huperzine A to (−)-Huperzine A includes: separating the (−)-Huperzine A from the racemic mixture of (±)-Huperzine A by chiral high performance liquid chromatography (HPLC), the chiral HPLC being performed utilizing a mobile phase including a solution including an alcohol and one selected from dichloromethane, trichloromethane, and a mixture thereof, and the chiral HPLC being performed utilizing a chiral stationary phase including a polysaccharide derivative.
一种将(±)-Huperzine A的外消旋混合物解析为(-)-Huperzine A的方法包括通过手性高效液相色谱法(HPLC)从(±)-Huperzine A的外消旋混合物中分离出(-)-Huperzine A,手性高效液相色谱法使用的流动相包括醇和选自二氯甲烷、三氯甲烷及其混合物的溶液,手性高效液相色谱法使用的手性固定相包括多糖衍生物。
