Sesquiterpenoids from Vernonia cinerea.
A new sesquiterpenoid, vernocinolide A (1), as well as ten known ones (2-11), were isolated from the ethyl acetate soluble fraction of Vernonia cinerea. The structure of vernocinolide A (1) was elucidated by spectroscopic methods. Among the known sesquiterpenoids, nine of them were isolated from this plant for the first time.
