Abstract:
Objective: To establish the identification method of Gegen Qinlian Preparation(Radix Puerariae, Radix Scutellariae, Rhizoma Coptidis, and Radix Glycyrrhizae) by three dimensional HPLC. Methods: Puerain, baicalin and berberine were dissolved with 70% methanol as a reference solution. Gegen Qinlian preparation was analysed by three dimensional HPLC, methanol water (27∶73 containing 0.7‰ sodium lauryl sulfate and 0.7‰ triethylamine) as a mobile phase was used by linear gradient elution. Conclusion: The scientific and well defined identification of three dimensional HPLC can be showed by Gegen Qinlian Preparation research and this method is accurate and reliable.
