title: [Study on lignans of Gentianella acuta].
abstract: OBJECTIVE
  To study the lignans from the whole plant of Gentianella acuta.
  
  
  METHODS
  The compounds were isolated by various chromatographic techniques and indentified by spectroscopic methods.
  
  
  RESULTS
  Nine compounds were isolated and identified as (7R,8S) -dehydrodiconiferyl alcohol-4,9'-O-beta-D-glucopyranoside (1), alaschanisoside A (2), citrusin A (3), olivil-4'-O-beta-D-glucopyranoside (4), leptolepisol D (5), acanthoside D (6), (+) pinoresinol-4-O-beta-D-glucopyranoside (7), (+) 8-hydroxypinoresinol-4-O-beta-D-glucopyranoside (8), and (+) pinoresinol-8-O-beta-D-glucopyranoside (9).
  
  
  CONCLUSIONS
  Compounds 1 - 9 are isolated from this plant for the first time, compounds 1 and 9 are isolated from Gentianella genus for the first time,and compounds 2, 3 and 5 - 8 are isolated from Gentianaceae family for the first time.
