| Abstract: | OBJECTIVE:To establish a method for determination of Schizandrol A in Schisandra chinensis (Turcz.) Baill. and its preparation.METHODS: HPLC was used .Inertsil ODS 3 C 18 column (250 mm×4.6 mm, 5um), methanol water ( 65:35) as mobile phase, with detection at 251nm,flow rate 1.0 m1·min -1 and column temperature at 25 ℃. RESULTS: The calibration curve was linear (r= 0.999 9), the mean recovery was 101.12%, the precision RSD was 0.92% (n=6).CONCLUSION: This method is simple, quick and specific, it provides a quality control methods for Schisandre chinensis and its preparetion. |
