    摘要: 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.
