[Abstract]
This study was aimed to establish the TLC identification method and HPLC characteristic chromatograms of Zhaoshanbai extract tablet, so as to provide a reliable method for scientific evaluation and effective quality control of this Chinese patent drug. Two kinds of phase system were adopted to establish the TLC for hyperin, quercetin and kaempferol of Zhaoshanbai extract tablet. The HPLC method was used to establish the liquid characteristic chromatogram of Zhaoshanbai extract tablet: with the peak of hyperoside as reference, ten samples were determined by HPLC method on a C18 column (250 mm × 4.6 mm, 5 μm) under the chromatographic conditions with acetonitrile (A) - 0.1% phosphoric acid solution (B) as gradient elution (0-13 min, 8%A; 13-28 min, 8%A→21%A; 28-46 min, 21%A; 46-60 min, 21% A→40%A; 60-77 min, 40%A; 77-80 min, 8%A) at a flow rate of 1.0 ml?min-1. The detection wavelength was 366 nm. The sample volume was 10 μl. The column temperature was 30℃ . The results showed that the sample was well indentified and separated. The HPLC specific chromatogram of Zhaoshanbai extract tablet had 12 common peaks. The peaks could be detected respectively. It was concluded that the established methods can realize a comprehensive and overall assessment, and provide a basis for improving the quality control of Zhaoshanbai extract tablet.
