title: [O-methylnotopterol, a new natural product from the roots and rhizomes of Notopterygium incisum].
abstract: OBJECTIVE
  To study the chemical constituents of ethyl acetate-soluble fraction from methanolic extract of the roots and rhizomes of Notopterygium incisum .
  
  
  METHODS
  The chemical constituents were isolated and purified by various chromatographic methods, and their structures were identified by NMR and MS data analysis.
  
  
  RESULTS
  Five compounds were obtained and identified as falcarindiol (1), 8-hydroxy-l-methoxy-( Z) -9-heptadecene-4, 6-diyn-3-one (2) angenomalin (3), scopoletin (4), O-methylnotopterol (5).
  
  
  CONCLUSIONS
  Compound 5 was a new natural product and compounds 2-4 were isolated from the roots and rhizomes of N. incisum for the first time.
