Comparison of Contents of Deoxyschizandrin and Schisantherrin A in Fructus Sch isandrae Chinensis / 中药新药与临床药理

ABSTRACT

Objective To establish a HPLC method for the determination of deoxys chizandrin and schisantherrin A in Fructus Schisandrae Chinensis. Methods The as say was conducted on a YWG-C18 column with methonal-water (77 ∶23) as mobile phase. The flow rate was 1.0 mL/min and detection wavelength was 230 nm. Results Satisfactory linearities of deoxyschizandrin and schisantherrin A were shown in the range of 0.125～1.25 ?g and 0.08～0.8 ?g,and the recovery was 100.1 %an d 100.0 %(RSD being 0.15 %and 0.28 %。Schisandra sphenanthcra),and 99.7 %an d 101.2 %(RSD being 0.32 %and 0.67 %。Schisandra chinensis) (n=5). Conclusion The HPLC method was simple,curate,highly sensitive and reproducible. It may b e used for the quantitative determination of deoxyschizandrin and schisantherrin A in Fructus Schisandrae Chinensis.
