title: [Chemical constituents from Rehmannia glutinosa].
abstract: OBJECTIVE
  To study the chemical constituents from the roots of Rehmannia glutinosa.
  
  
  METHODS
  The compounds were isolated by various chromatographic methods and identified by spectroscopic analysis.
  
  
  RESULTS
  Twelve compounds were isolated and their structures were identified as 5-hydroxymethyl-pyrrole-2-carbaldehyde (1), 5-hydroxymethyl furfural (2), tyrosol (3), 5,6-dihydroxy-beta-ionone (4), 6-O-E-feruloyl ajugol (5), acteoside (6), leucosceptoside A (7), martynoside (8), isomartynoside (9), purpureaside C (10), jionoside A1 (11), and jionoside B1 (12).
  
  
  CONCLUSIONS
  Compounds 1, 3 and 9 were isolated from the genus Rehmannia for the first time.
