title: [Identification of dihydroflavonol glycoside isomers in Smilax glabra by HPLC-MS and HPLC-1H NMR].
abstract: OBJECTIVE
  To identify dihydroflavonol glycoside isomers in Smilax glabra.
  
  
  METHODS
  The sample was analyzed by HPLC-MS in combination with HPLC-1H-NMR.
  
  
  RESULTS
  Four dihydroflavonol glycoside isomers were identified as astilbin, neoastilbin, isoastilbin, neoisoastilbin.
  
  
  CONCLUSIONS
  The method is simple and rapid for the identification of dihydroflavonol glycosides in S. glabra.
