Objective: A micellar electrokinetic capillary chromatography(MEKC) was developed for the rapid determination of six lignans in Schisandra chinensis. Method: The key factors for separation and determination were studied and the best analysis conditions were obtained
in the background electrolyte of 10 mmol·L-1 phosphate(35% acetonitrile
37.5 mmol·L-1 SDS
pH 8.0) at the separation voltage of 28.0 kV
the Schisandra extract could be detected within 6 min. Result: The lignans showed good linear response in the range of 25.5-1 020
25.75-1 030
12.0-480
25.5-1 020
24.25-970 and 19.75-790 mg·L-1
the limit of detection was 0.5
0.8
1.0
1.0
1.0 and 1.5 mg·L-1. Conclusion: Compared with high-performance liquid chromatography(HPLC)
the MEKC analyses offers high separation efficiencies and rapid analyses.
