Three stigmastane-type sterols and one ergostane-type sterol were isolated from the ethyl acetate soluble fraction of the aerial parts of Artemisia princeps Pampanini (Sajuarissuk). From the results of physico-chemical data including NMR, MS and IR, the chemical structures of the compounds were determined as $stigmasta-5,22-dien-3,{eta}-ol (stigmasterol, 1),stigmast-5-en-3{eta}-ol({eta}-sitosterol,2), 5{eta},8{eta}-epidioxy-5{eta},8{eta}-ergosta-6,22-dien-3{eta}-ol(ergosterol peroxide, 3),;and;{eta}-sitosterol;3-O-{eta}D-glucopyranoside(daucosterol,4)$.
