Abstract
A new sesquiterpene lactone ( 1) and a new aromatic glycoside ( 2), together with three known compounds ( 3– 5) were isolated from the stem bark of Illicium difengpi K. I. B et K. I. M. Their structures were determined by spectroscopic methods, including 1D and 2D NMR, HRESIMS, and chemical methods. The absolute configuration of the secondary alcohol in 1 was confirmed by Mosher's method. Compound 2 exhibited significant anti-inflammatory activity with IC 50 value of 6.72 μmol/L.
