| Abstract: | Following an initial clean-up step on a Sephadex LH-20 column, high-speed countercurrent chromatography was successfully applied to the isolation and purification of three flavonoids from a crude sample of Helichrysum arenarium (L.) Moench. HSCCC was performed with a two-phase solvent system composed of ethyl acetate–water (1:1, v/v). Naringenin-7-O-β-d-glycoside (2.3 mg), isoquercitrin (3.5 mg), and astragalin (6.7 mg), with purities of 96.05%, 93.63%, 95.23%, respectively, were separated from 160 mg of crude sample in a one-step separation. The structure identification was by 1H NMR and 13C NMR. |
