Abstract Four new sesquiterpenoids, artemyrianins A-D (1-4), and three new norlignans, artemyrianins E-G (5-7), together with five known compounds (8-12), were isolated from the aerial parts of Artemisia myriantha (Asteraceae). The new compounds were established by spectroscopic data analyses (HRMS, IR, 1D and 2D NMR), and their absolute configurations were confirmed by the single-crystal X-ray diffraction or ECD calculations. The isolates showed cytotoxicity against HepG2 cells with IC50 values ranging from 33.3 to 145.2 μM.
