Anti-inflammatory polyphenol constituents derived from Cissus pteroclada Hayata

The structure of new bergenin derivative, bergenin-11-O-α-d-galactopyranoside (1) isolated from the stem of Cissus pteroclada Hayata has been determined by detailed spectroscopic analyses. The in vitro anti-inflammatory activity assay of the compounds 1–8 indicated that bergenin derivatives (1–4) exhibited significant anti-inflammatory effects via modulation of NF-κB activation.
