【Abstract】 Objective: To investigate the chemical constituents in flower bud of Artemisia scoparia . Method: The methanol extract was isolated by column chromatography with silica gel, polyamide and Sephadex LH-20 as packing materials and HPLC, six compounds were obtained and their structures were identified by UV, NMR and MS. Result: Six compounds were identified as β-sitosterol(Ⅸ), 6,7-dimethoxycoumarin(Ⅹ), 6-demethylcapillarisin(Ⅺ), capillartemisin B(Ⅻ), kumatakenin(), isoscoploletin-β- D -glucoside(). Conclusion: Ⅺ, Ⅻ,  and  were obtained from the plant for the first time, and Ⅺ is a new compound.更多还原
