Study on the chemical constituents of vinegar Schisandra chinensis

To study the chemical constituents of vinegar Schisandra chinensis.Column chromatography was used in the isolation procedure. The structures of isolated compounds were elucidated by spectral data.Five compounds were isolated and their structures were identified as kadsuranin (I), beta-sitosterol (II), schizandrin (III), 5,5'-[oxybis (methylene)] bis-2-furancarboxaldehyde (IV) and (NH)-form-2-Hydroxyquinoline4-carboxylic acid (V).Compound 5 is isolated from this genus for the first time.
