[O-methylnotopterol, a new natural product from the roots and rhizomes of Notopterygium incisum].
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
