Abstract:
OBJECTIVETo investigate the chemical constituents in flower bud of Artemisia scoparia.
METHODThe 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.
RESULTSix compounds were identified as beta-sitosterol (IX), 6,7-dimethoxycoumarin (X), 6-demethylcapillarisin (XI), capillartemisin B (XII), kumatakenin (XIII), isoscoploletin-beta-D-glucoside (XIV).
CONCLUSIONXI, XII, XIII and XIV were obtained from the plant for the first time, and XI is a new compound.
