Assessment of two centrifugal partition chromatography devices. Application to the purification of Centaurium erythraea methanolic extract

Two different centrifugal partition chromatography devices, Spot CPC and Quantum CPC, have been evaluated for the purification of swertiamarin from a methanolic extract of Centaurium erythraea. By using the same solvents system on isocratic and gradient mode, enriched fractions have been obtained and examined by HPLC-UV. The results are discussed, as well as various parameters such as rotation speed, flow rate and productivity.
