title: [Flavonoids and nor-sesquiterpenes of Pedicularis densispica].
abstract: OBJECTIVE
  To study the chemical constituents of the whole plants of Pedicularis densispica.
  
  
  METHODS
  The chemical constituents were isolated by various chromatographic methods and their structures were determined by chemical evidences and spectral data.
  
  
  RESULTS
  Ten compounds were isolated and identified as acacetin (1), apigenin-7-0-beta-glucopyranoside (2), kaempferol-3,7-O-alpha-dirhamnopyranoside (3), scutellarein-7-0-beta-glucopyranoside (4), chrysoeriol-7-O-beta-glucopyranoside (5), pedicutricone A (6), dearabinosyl pneumonanthoside (7), salidroside (8), darendoside B (9), and maltol-beta-D-glucopyranoside (10).
  
  
  CONCLUSIONS
  These compounds were isolated from the titled plant for the first time. Except compounds 6 and 8, the others were obtained for the first time from the genus Pedicularis.
