Sesquiterpenoids from Lactuca tatarica.
A new guaianolide and a new eudesmanolide were isolated from Lactuca tatarica, as well as eight known sesquiterpenoids. The new compounds were elucidated on the basis of spectroscopic methods including IR, HRESIMS, 1D and 2D NMR, and the known compounds were established by comparing their physical data with those of the corresponding compounds in the literature.
