ABSTRACT
Based on UPLC specific chromatogram and determination of seven main components,this study aimed at evaluating the quality of Cistanche deserticola,C. tubulosa and C. sinensis. Echinacoside,cistanoside A,verbascoside,tubuloside A,isoacteoside,2'-acetylacteoside,tubuloside B were used as reference substances. UPLC analysis was performed on a Waters ACQUITY UPLC HSS T3 column( 2. 1 mm×100 mm,1. 8 μm). The mobile phase was acetonitrile-0. 08% trifluoroacetic acid solution. The flow rate was0. 3 mL·min-1,and the injection amount was 10 μL. The column temperature was 40 ℃,and the detection wavelength was 330 nm.The UPLC specific chromatograms were processed with ChemPattern software. UPLC specific chromatograms of C. deserticola and C.tubulosa from different samples were of high similarity,but the similarities of their counterfeit C. sinensis were less than 0. 06. Both of cluster and principal component analysis can distinguish certified products and counterfeits. The content ratios of echinacoside/verbascoside and verbascoside/isoacteoside were quite different between C. deserticola and C. tubulosa,which had distinct significance.The UPLC specific chromatogram and contents of seven main components can provide a basis for quality evaluation of Cistanches Herba.
