title: [Studies on isolation and identification of flavonoids in herbs of Agrimonia pilosa].
abstract: OBJECTIVE
  To study the chemical constituents in Agrimonia pilosa.
  
  
  METHODS
  The compounds were isolated and purified by various column chromatographic methods and elucidated on the basis of chemical and spectroscopic evidences.
  
  
  RESULTS
  Nine flavonoids were obtained and identified as tiliroside (1), kaempferol 3-O-alpha-L-rhampyranoside (2), quercetin 3-O-alpha-L-rhampyranoside (3), quercetin 3-O-beta-D-glucopyranoside (4), kaempferol 3-O-beta-D-glucopyranoside (5), kaempferol (6), apigenin (7), luteolin (8), quercetin (9).
  
  
  CONCLUSIONS
  Compounds 1-3, 5, 6 and 8 were isolated from this plant for the first time.
