title: [Identification of major components of traditional Chinese medicine Naodesheng tablet by HPLC-DAD-MS(n)].
abstract: To identify the major components of traditional Chinese medicine Naodesheng tablet.
  
  
  
  A HPLC-DAD-MS(n) based method was developed to analyze and identify the major components of Naodesheng tablet. Separation was performed on an Agilent Zorbax SB-C(18) column (4.6 mm X 250 mm, i.d, 5 μm) with mobile phase consisting of water with 0.05 % formic acid and acetonitrile as gradient eluent at the flow rate of 0.5 ml.min(-1).
  
  
  
  A total of 43 components were detected, among which 22 were identified by comparing their UV absorption profiles, the information of molecular Glucosyl puerarin weights, and structures provided by ESI-MS(n) with those of available standards and reference data, such as Safflor yellow A, 4'-O-Glucosyl puerarin, 3'-hydroxypuerarin, Genistein-8-C-apiosyl (1-6) glucoside, Puerarin, 6"-O-xylosyl puerarin, 6"-O-apiosyl puerarin, 3'-methoxy puerarin, 3'-methoxy-6"-o-xylosyl puerarin, Daidzin, Genistin, Pueroside A, Notoginsenoside R(1), Ginsenoside Re, Ginsenoside Rg1,Daidzein,Biochanin A,Ginsenoside Rb(1), Ginsenoside Rc, Ginsenoside Rb(2), Ginsenoside Rb(3), Ginsenoside Rd.
  
  
  
  The proposed method can identify the main components of Naodesheng tablet and provide information for the quality control of this medicine.
