title: [Chemical constituents of Notoseris rhombiformis].
abstract: OBJECTIVE
  To investigate the chemical constituents from the whole plant of the endemic plant Notoseris rhombiformis Shih.
  
  
  METHODS
  Column chromatography was used for separation and purification, while spectral analysis was used for structure elucidation.
  
  
  RESULTS
  Eight compounds were isolated from the whole plant of this Chinese endemic plant and their structures were elucidated as notoserolide A (1), notoserolide D (2), austricin (3), jacquilenin (4), 3 beta, 14-dihydroxy-11 beta, 13-dihydrocostunolide (5), p-hydroxyphenylacetic acid (6), luteolin-7-O-beta-D-glucopyranoside (7) and daucosterol (8), respectively.
  
  
  CONCLUSIONS
  All compounds were isolated from this plant for the first time. Among them, 2 is a new compound.
