Abstract: Objective To develop a new method for the isolation and purification of cordycepin by high speed counter-current chromatography (HSCCC) with Cordyceps militaris fermentation broth as raw material. Methods The solvent systems for cordycepin separation were assessed and selected by HPLC partition coefficient method and analytical HSCCC. A solvent system that consisted of ethyl acetate-n-butanol-0.5% ammonia water (2:3:5) was applied to the separation. The upper phase was used as the stationary phase, while the lower phase was used as the mobile phase for the cordycepin separation by HSCCC. Results A high efficiency of HSCCC separation was achieved. Finally, cordycepin (43.8 mg) was obtained from 400 mg crude extract of C. militaris fermentation broth in one-step separation with a purity of 98.7%. Conclusion HSCCC is an efficient and simple method for the largescale preparation of cordycepin from C. militaris fermentation broth, which could provide the material basis for the pharmacological research of cordycepin .
