Structure Elucidation of A N ew I ridoid from Artemisia integrifolia

The ether extract of Artemisia integrifolia was 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 ( 1 H NMR and 13 C NMR) and 2D-NMR (COSY, HSQC and NOESY) spectral analysis.
