A new guaianolide, 1S, 35, 5R, 6S, 7S, 11R-1-hydroxy-11 alpha,13-dihydrozaluzanin C (1), was isolated from Moquiniastrum polymorphum subsp. floccosum trunk bark, together with fifteen known compounds, which were identified as 1 la,13-dihydroglucozaluzanin C (2), 8 alpha-hydroxy-11 alpha.,13-dihydrozaluzanin C (3), zaluzanin C (4), gochnatiolide B (5), ethyl caffeate (6), methyl chlorogenate (7), ethyl chlorogenate (8), methyl 3,5-dicaffeoyl quinate (9), ethyl 3,5-dicaffeoyl quinate (10), methyl 4,5-dicaffeoyl quinate (11), ethyl 4,5-dicaffeoyl quinate (12), ethyl 3,4-dicaffeoyl quinate (13), 3,5-dicaffeoyl quinic acid (14), 4,5-dicaffeoyl quinic acid (15), and 3,4-dicaffeoyl quinic acid (16). With the exception of 5, all known compounds are being reported for the first time in M polymorphum.
