Abstract
Two new terpenoids have been isolated from the aerial parts of Artemisia sacrorum Ledeb. The structure elucidation of two new compounds was carried out by 1D (1H nuclear magnetic resonance [NMR] and 13C NMR) and 2D-NMR (correlation spectroscopy [COSY], heteronuclear single-quantum correlation [HSQC], heteronuclear multiple-bond correlation [HMBC] and nuclear Overhauser effect spectroscopy [NOESY]) spectral analysis. Key words: Artemisia sacrorum, terpenoid, nuclear magnetic resonance (NMR), high-resolution electrospray ionization mass spectrometry (HR-ESI-MS).
Highlights
Artemisia sacrorum is a member of the family composite and distributed throughout Inner Mongolia of China (Wang and Jin, 2010)

Summary
Artemisia sacrorum is a member of the family composite and distributed throughout Inner Mongolia of China (Wang and Jin, 2010). This paper describes the isolation and structure elucidation of the new compounds. NMR spectra were measured on a Bruker AV–500 spectrometer (Bruker, Germany) with tetramethylsilane (TMS) as the internal reference, and chemical shifts are expressed in δ (ppm).
