Abstract

Seven compounds (1-7) were isolated from n-hexane and EtOAc-soluble fractions of the roots of Erigeron annuus by repeated silica gel column chromatography. They were identified as simiarenol (1), ${\beta}$-sitosterol (2), daidzein (3), apigenin (4), apigenin 7-O-${\beta}$-D-glucuronide (5), 3-hydroxy-pyran- 4-one (6), and ${\beta}$-sitosterol glucoside (7) on the basis of physical and spectroscopic data. Compounds 1 and 3 were isolated for the first time from the Erigeron species.
