Open publisher page 1 citations

Abstract

Objective To prepare swertiamarin with high purity from Swertia mussotii Franch.with macroporous resin and flash chromatography.Methods Herba S.Mussotii was extracted with ethanol solvent.The extract solvent was adsorpted and separated with HPD-300 to obtain crude extract of swertiamarin,then the crude extract is purified with flash chromatography.Results The purity of swertiamarin was more then 90%;recovery rate was 79.94%.Conclusion The preparation method established in this experiment can be operated easily with good reproducibility and high recovery rate.The purity of the swertiamarin can be up to 90%.
