Abstract

A TLC method for identification of radix paeoniae rubra, radix salviae miltiorrhizae, radix scutellariae, poria and rhizoma sparganii in Chidan pills and a HPLC method for determination of paeonflorin in pills were presented. A Diamonsil C_ 18 column was used with the mobile phase of acetonitrile-water (20∶80), at room temperature and detection wavelength of 230 nm. The calibration curve of paeonflorin was linear in the concentration range of 16～160 μg/ml( r=0.9999) .The average recovery was 99.1% with RSD of 2.09%.
