[Studies on chemical constituents in bud of Artemisia scoparia (II)].
OBJECTIVE
To investigate the chemical constituents in flower bud of Artemisia scoparia.


METHODS
The constituents were isolated and purified by means of various chromatographic methods, and spectroscopic methods were used to identify their structures.


RESULTS
Four flavones were isolated and their structures were identified as hyperin (V), eupafolin (VI), pedalitin (VII), 5,7,2',4'-tetrahydroxy-6,5'-dimethoxyflavone (VIII).


CONCLUSIONS
Compounds V, VI, VII, VIII were obtained from this plant for the first time.
