Abstract

The novel melampolides (11R)-11,13-dihydro-schkuhriolide (7), (11S)-11,13-dihydro-schkuhriolide (8), and schkuhrioidiol (11), along with the known constituents, frutescin (1), schkuhriolide (2), frutescinic acid (4), allo-schkuhriolide (5), and epoxyschkuhriolide (6) were isolated from the aerial parts of Schkuhria schkuhrioides. The structures of the new compounds were determined by spectroscopic methods. Compounds 1, 2, 4, 5, and 6 displayed no significant cytotoxic or antimicrobial activities.
