Li HB, Chen F: Preparative isolation and purification of salidroside from the Chinese medicinal plant Rhodiola sachalinensis by high-speed counter-current chromatography. Journal of Chromatography A 2001, 932(1-2):91-95.

High-speed counter-current chromatography was applied to the isolation and purification of salidroside from the Chinese medicinal plant Rhodiola sachalinensis A. Bor. The crude salidroside was obtained by extraction with methanol from Rhodiola sachalinensis A. Bor. Preparative high-speed counter-current chromatography with a two-phase solvent system composed of n-butanol-ethyl acetate-water (2:3:5, v/v) was successfully performed yielding salidroside (32 mg) at 98% purity from 250 mg of the crude extract in a one-step separation.
