UPLC fingerprints of Bushen Qiangshen Tablets / 中成药

ABSTRACT

AIM To establish the UPLC fingerprints of Bushen Qiangshen Tablets (Epimedii Folium,Cuscutae Semen,Rosae Laevigatae Fructus,etc.).METHODS The analysis of 50％ ethanol extract of this drug was performed on a 40 ℃ thermostatic Agilent SB-C18 column (100 mm ×4.6 mm,2.7 μm),with the mobile phase comprising of acetonitrile-0.1％ phosphoric acid flowing at 0.5 mL/min in a gradient elution manner,and the detection wavelength was set at 215 nm.Then the fringerprints were evaluated by cluster analysis,principal components analysis and orthogonal partial least squares discriminant analysis.RESULTS There were twenty common peaks in the UPLC fingerprints of twelve batches of samples,nine of which (protocatechuic acid,salidroside,chlorogenic acid,hyperin,specnuezhenide,epimedin C,icariin,kaempferide and baohuoside Ⅰ) were identified,with the similarities of 0.843-0.970.Twelve batches of samples could be divided into three types,and four differential markers,including specnuezhenide and chlorogenic acid,were found out.CONCLUSION This simple and reliable method can be used for the quality control of Bushen Qiangshen Tablets.
