Three new eudesmanes, named artemisidiols A-C, together with eight known compounds, were isolated from the leaves of Artemisia japonica Thunb. (Asteraceae). Their structures were determined on the basis of spectroscopic data. Although oxygenated eudesmanes frequently occur in Asteraceae plants, the 1α,6α,8α-oxygenated pattern of artemisidiols A-C has not been previously reported.
