Abstract
Phytochemical investigation on the pericarps of Illicium difengpi lead to the isolation and structure elucidation of a new sesquiterpene, sesquicaranoic acid C (1), a new neolignan, difengpiol C (2), and 10 known compounds. The structures and absolute configurations of two new compounds were determined by a combination of NMR and CD spectroscopic analyses. All isolates were evaluated for their inhibitory effects on lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW264.7 cells.
Keywords:
Illicium difengpi; anti-inflammatory; neolignan; sesquiterpene.
