High-speed counter current chromatograph

An optimized high-speed counter-current chromatographic (CCC) technique was described for the isolation of [6]-, [8]-and [10]-gingerols, in quantities between 40 and 500 mg, from powdered root ginger. Minor modifications to the procedure allowed the separation of [4]-gingerol. The purity of the isolated gingerols was assessed by proton NMR. Of the four gin-...
