Abstract
Mangiferin was separated from rhizomes of Anemarrhena asphodeloides extract using centrifugal partition chromatography (CPC) with a two‐phase solvent system composed of ethyl acetate‐isopropanol‐water (3∶2∶5, v/v). Mangiferin (22.5 mg) was successfully isolated from methanolic extracts (957 mg) in only one step, and the purity of isolated compound was determined to be over 95% by HPLC analysis. The structure of mangiferin was identified by 1H, 13C NMR and ESI‐MS spectral data analysis.
