A simple, rapid, and specific HPLC method was established for simultaneous determination of five major lignans (Schizandrol A,Schizandrol B,Schisandrin A,γ-Schisandrin, andSchisandrin C) inSchisandra chinensis. The five lignans can be separated completely on Kromasil C18column (250 nm × 4.6 nm) and then detected at 254 nm using methanol (mobile phase A) and water (mobile phase B) with gradient elution as the mobile phase at 1.0 mL/min flow rate. The column temperature was 30°C. The method was validated in terms of linearity, precision, stability, repeatability, and recovery. Results showed that the method is accurate and reproducible.

In contrast to the adjustment of single plates a block adjustment is a simultaneous determination of all unknowns associated with many overlapping plates (star positions and plate constants etc. ) by one large adjustment. This plate overlap technique was introduced by Eichhorn and reviewed by Googe et. al. The author now has developed a set of computer programmes which allows the adjustment of any set of contemporaneous overlapping plates. There is in principle no limit for the number of plates, the number of stars, the number of individual plate constants for each plate, and for the overlapping factor.
