RESUMO

Objective A fingerprint of Rhizoma Alismatis Orientalitis' decoction pieces was established by HPLC-ELSD. Methods The gradient elution mode was applied in chromatographic separation by mobile phase of methanol and water at flow rate of 0.5 mL? min-1 in a Diamonsil TM C18 chromatographic column (250 mm ? 4.6 mm, 5 ? m), and recording time was 70 minute. The parameters of evaporative light scattering detector were set as follows: the temperature of the drift tube was 82.5 ℃ and gas flow rate was 1.9 L ? min-1.The data was analyzed with cluster analysis and similarity calculation software. Results The fingerprint showing 15 common peaks was obtained. The results of cluster analysis and similarity calculation showed there existed differences in fingerprints of 16 batchers of medicinal slices of Rhizoma Alismatis Orientalitis. Conclusion The method is effective and reproducible for the quality control of medicinal slices of Rhizoma Alismatis Orientalitis.
