Five compounds of terpenoids and coumarins were isolated from the non-polar fraction of Artemisia apiacea by open column chromatography. Their structures were elucidated as $alpha$-amyrin (1), $eta$-amyrin (2), $eta$-sitosterol (3), 5,6,7-trimethoxycoumarin (4) and 6-methoxy-7,8-methylenedioxycoumarin (5) by chemical and spectroscopic analysis. This is the first report of the isolation of $alpha$-amyrin, $eta$-amyrin, 5,6,7-trimethoxycoumarin and 6-methoxy-7,8-methylene-dioxycoumarin from this plant.
