Abstract:Objective To establish the quality standard of Changkang Capsules. Methods Thin layer chromatography (TLC) was used to identify Coptidis Rhizoma, Aucklandiae Radix, Draconis Sanguis and Corydalis Rhizoma. Meanwhile, high performance liquid chromatography (HPLC) was used to determine the effective components of berberine and bamatine in Coptidis rhizoma. the chromatographic conditions were: Angilent XDB-C18 column (4.6 mm × 150 mm, 5 μm), acetonitrile-0.05 mol/L KH2PO4 (50∶50, v/v) (added 0.4 g of sodium dodecyl sulfate into every 100 mL solution, then adjusted the pH value to 4.0 with H3PO4), 1.0 mL/min, 345 nm, room temperature, 10 μL. Results TLC identification spots were clear and the negative control had no interference. The effective component of berberine in Coptidis rhizoma had good linear relationship in the range of 29.4-98.0 μg/mL. The average recovery was 101.00%, and the precision RSD was 0.93%. The effective component of bamatine in Coptidis Rhizoma had good linear relationship in the range of 7.1-31.8 μg/mL. The average recovery was 99.68%, and the precision RSD was 0.80%. Conclusion The research results show that this method can be used for the quality control of Changkang Capsules.
