Sesquiterpenoids from Artemisia vestita and Their Antifeedant and Antifungal Activities.


ABSTRACT: Four new sesquiterpenoids, named artemivestinolide D-G (1-4) and three known sesquiterpenoids (5-7), were isolated from Artemisia vestita. The structures of these new compounds were determined based on extensive spectroscopic data analyses. Furthermore, the electronic circular dichroism data determined the absolute configurations of the new compounds. The antifeedant and antifungal activities of the isolates were evaluated against third-instar larvae of Plutella xylostella and three plant pathogenic fungi. Compounds 1-7 showed moderate antifeedant activities and compounds 1-4 and 6-7 exhibited antifungal activities.
