Abstract:Objective To establish a quality control method for Ma′nao Gao. Methods Thin layer chromatography was applied to the qualitative identification of Faeces Togopteri, Corydalis Rhizoma, Rhei Radix et Rhizoma, Psoraleae Fructus, Notoginseng Radix et Rhizoma. High performance liquid chromatography was used for the content determination of tetrahydropalmatine, acetonitrile-0.1% triethylamine phosphate system was used as the mobile phase of gradient elute. The column temperature was 30°C and the detection wavelength was set at 280 nm. Results Thin layer chromatography spots was clear, which had good resolution without interference. Tetrahydropalmatine had good linear relationship with the range of 2.022-20.22 μg/mL (r = 0.9999) respectively, the average recovery was 100.27% (RSD = 2.39%). Conclusion The method is reliable with good stability and good repeatability, and can be used for quality control of Ma′nao Gao.
