The aerial parts of Artemisia eriopoda (Compositae) afforded two new C (17)-polyacetylenes. Based on their IR, UV, EIMS, (1)H- and (13)C-NMR (DEPT) spectral data, the structures were elucidated to be (1,8 E,13 Z,16)-heptadecatetraene-4,6-diyne-3,11,12-triol and (1,8 E,12 E,14 Z)-heptadecatetraene-4,6-diyne-3,11-diol.
