Objective: To investigate the chemical constituents in flower bud of Artemisia scoparia.
Method: The constituents were isolated and purified by means of various chromatographic methods, and spectroscopic methods were used to identify their structures.
Result: 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).
Conclusion: Compounds V, VI, VII, VIII were obtained from this plant for the first time.
