ABSTRACT
AIM:
To establish a reversed-phase HPLC method of determining three kinds of berberine type alkaloids(jatrorrhizine,palmatine and berberine) in Rhizoma Coptidis and Jinqi Jiangtang Tablet(Flos Lonicerae japonicae,Rhizoma Coptidis and Radix Astragali)METHODS:
RP-HPLC was used for determination.The separation was carried out on Diamonsil C_(18)column(4.6 mm?250 mm,5 ?m) with the mobile phase containing acetonitrile-0.1 mol/L potassium dihydrogen phosphate(30(∶)70) and a detective wavelength was at 345 nm.The flow rate was 1.0 mL/min.RESULTS:
The average contents of jatrorrhizine,palmatine and berberine in Rhizoma Coptidis and Jinqi Jiangtang Tablet were 1.34%,1.61%,7.12% and 0.35%,0.64%,1.54% respectively.CONCLUSION:
The method is simple,accurate with a good recovery and repeatability and can be used to control the quality of Rhizoma Coptidis and Jinqi Jiangtang Tablet.
