Six major lignans (schizandrin, gomisin A, deoxyschizandrin, ?-schizandrin, gomisin N, wuweizisu C) in the caulomas and leaves of Schizandra chinensis (TURCZ.) BAILL., and cinnamic acid in the leaves of the plant, were quantitatively analysed by high performance liquid chromatography in reverse phase mode with UV detection. Resolution of the determined lignans was evaluated for two multistep gradients applied. Samples for HPLC analysis were prepared by extraction with supercritical carbon dioxide at pressures 20-27 MPa and temperatures 40-60 oC. Kinetics of the extraction of individual components was measured and simulated with a model.
