title: [Studies on dihydroflavonol glycosides from rhizome of Smilax glabra].
abstract: OBJECTIVE
  To investigate the chemical constituents from the rhizomes of Smilax glabra.
  
  
  METHODS
  The compounds were isolated by column chromatography with silica gel, Diaion HP-20 and ODS as packing materials, and HPLC. Their structures were determined on the basis of their spectral evidence.
  
  
  RESULTS
  5 dihydro-flavonol glycosides were identified as: astilbin (1), neoastilbin (2), isoastilbin (3), neoisoastilbin (4), (2R, 3R)-taxifolin-3'-O-beta-D-pyranglucoside (5).
  
  
  CONCLUSIONS
  Compounds 2, 4, 5 were isolated from this plant for the first time.
