Two new sesquiterpenes, together with 32 known compounds(3–34), were isolated from Artemisia sieversiana Ehrhart ex willd. and the compounds 3–21 were isolated from this plant for the first time. The new compounds were elucidated as 2α,9α-dihydroxymuurol-3(4)-en-12-oic acid (1) and 13α-methyl-(5αH,6αH,7αH,8αH)-austricin 8-O-β-D-glucopyranoside (2), respectively. The structural identification of these compounds was mainly achieved by spectroscopic methods including 1D and 2D NMR techniques, and the structure of compound 1 was confirmed by a single crystal X-ray diffraction experiment. Compounds 1–2 were evaluated for cytotoxic activity in vitro against MCF-7, NCI-H460 and Hep-G2 cell lines, respectively.
