title: [Studies on chemical constituents in roots and rhizomes of Notopterygium incisum].
abstract: OBJECTIVE
  To study the chemical constituents in the roots and rhizomes of Notopterygium incisum.
  
  
  METHODS
  The chemical constituents were isolated by various column chromatographic methods and structurally elucidated by NMR and MS evidences.
  
  
  RESULTS
  Twenty-four compounds were obtained and identified as isocalamenediol (1), pregnenolone (2), beta-sitosterol (3), bergapten (4), bergaptol (5), cnidilin (6), isoimperatorin (7), bergamottin (8), demethylfuropinnarin (9), nodakenetin (10), 7'-O-methylnotoptol (11), notopterol (12), notoptol (13), pabulenol (14), phenethylferulate (15), p-hydroxyphenethyl anisate (16), trans-ferulic acid (17), nodakenin (18), sucrose (19), 2-methoxy-4-(3-methoxy-1-propenyl)-phenol (20), 3, 4, 5 trimethoxy-trans-cinnamic acid (21), p-methoxycinnamic acid (22), 4-acetoxy-3-methoxy-trans-cinnamic acid (23), and p-hydroxy-trans-cinnamic acid (24).
  
  
  CONCLUSIONS
  Compounds 1, 14, 20-24 were isolated from the roots and rhizomes of N. incisum for the first time. Compounds 1 and 14 are sesquiterpenoid and coumarin, respectively, and 20-24 were phenylpropanoid compounds.
