Monoterpenoids from Seriphidium transiliense and their Biological Activity.

Ten monoterpenoids, including new seritramentol A (1), were isolated from Seriphidium transiliense (Poljakov) Poljakov. Compounds 2, 3, 6, and 7 were isolated from this plant as new natural compounds that were previously synthesized. The structures of the compounds were elucidated by analyzing HR-ESI-MS, UV, IR, and 1D and 2D NMR spectra and calculating ECD spectra. Their absolute configurations were established for the first time. The isolated compounds were tested for antimicrobial, anti-inflammatory, and antioxidant activity. [ABSTRACT FROM AUTHOR]
