Abstract: The ether extract of Artemisia integrifoliawas separated by chromatography and afforded a new iridoid, arteintegin A (6), together with five known compounds, namely chamazulene (1) , acetylenes (E)-2, (E)-3, (Z)-4, eugenol (5). The structure elucidation of the new compound was carried out by 1D ( 1H NMR and 13C NMR) and 2D-NMR (COSY, HSQC and NOESY) spectral analysis .
