To establish a method for fingerprinting of Fuzhisan (FZS, a traditional Chinese medicinal preparation) using high-performance liquid chromatography with ultraviolet and evaporative light scattering detector (HPLC-UV/ELSD) to allow simultaneous determination of 5 major constituents in the preparation. HPLC-UV/ELSD analysis was performed on water AlltechC18 column (5 microm, 4.6 mm x 250 mm) with a mixture of acetonitrile (A) and 0.1% acetice acid water (B) as the mobile phase. The solvent A gradient for elution was 0, 12%; 25, 20%; 30, 20%; 75, 30%; 105, 40%; 120, 80%; 130, 12%, with the flow rate of 1.0 ml/min; and the column temperature at 30 degrees . The detective wavelength was 335 nm, drift tube temperature was 80 degrees , pressure of nebulizer gas was 25 psi. The similarities between the HPLC-UV/ELSD fingerprints of the 12 extracts were calculated using similarity evaluation software. The fingerprint of FZS was established and the 5 major constituents were identified. The complementarity between the f
