title: [Flavonoid glycosides from Androsace umbellata].
abstract: OBJECTIVE
  To study the chemical constituents of Androsace umbellata.
  
  
  METHODS
  Many chromatography means were used in separation and purification, and the structures of all compounds were identified by the means of spectroscopic analysis and physico-chemical properties.
  
  
  RESULTS
  10 compounds were elucidated as kaempferol 3-O-(3-O-acetyl-)-alpha-L-rhamnopyranoside(1), kaempferol 3-O-(2-O-acetyl-)-alpha-L-rhamnopyranoside(2), kaempferol 7-O-alpha-L-rhamnopyranoside(3), kaempferol 3-O-alpha-L- rhamnopyranoside(4), kaempferol 3-O-beta-D-glucopyranoside(5), kaempferol 3-O-(3-O-acetyl-)-a-L-rhamnopyranosyl-7-O-alpha-L- rhamnopyranoside(6), kaempferml 3-O-(4-O-acetyl-)-alpha-L-rhamnopyranosyl-7-O-alpha-L-rhamnopyranoside(7), quercetin 3-O-alpha-L- rhamnopyranoside(8), quercetin 3-O-beta-D-glucopyranoside(9) and myricetin 3-O-beta-D-glucopyranoside (10), respectively.
  
  
  CONCLUSIONS
  All compounds were obtained from the title plant for the first time.
