title: [Chemical constituents from Gentiana striata].
abstract: OBJECTIVE
  To study the chemical constituents of Gentiana striata.
  
  
  METHODS
  The constituents were isolated from the whole herb of Gentiana striata by recrystalization, silica gel column chromatography, polyamide column chromatography and Sephadex LH-20,etc. Their structures were elucidated through MS, 1H-NMR, 13C-NMR.
  
  
  RESULTS
  -8 compounds were isolated and identified as: Desoxyloganin (1), Gmephiloside (2), 5,7,4'-trihydroxy-3'-methoxyflavone (3), (+)-8-hydroxypinoresinol (4) 3S,5R, 6R, 9S-tetra-hydroxymegastigmane (5), Quercetin-3-O-beta-D-glucoside (6), Ferulic acid (7) and Ursolic acid (8).
  
  
  CONCLUSIONS
  All the compounds are isolated for the first time from Gentiana striata.
