A commercial model of the analytical high-speed counter-current chromatography instrument was used for separation of flavonoids from a crude ethanol extract of dried fruits of sea buckthorn (Hippophae rhamnoides). Using a two-phase solvent system of chloroform-methanol-water (4:3:2), a five-fold inc
