MAGUIRE and its variety incana (GRAY) HULTÉN two new naturally occuring pseudoguaianolides were isolated and their structures established by spectroscopic methods. They are shown to be 4-O-acetyl-6-desoxychamissonolide (3) and the propionylic ester of 11,13-dihydrohelenalin which was named arnicolide G (6).
