Dihydroberberine, a hydrogenated derivative of berberine firstly identified in Phellodendri Chinese Cortex, exerts anti-inflammatory effect via dual modulation of NF-κB and MAPK signaling pathways

Dihydroberberine (DHB), a hydrogenated derivative of berberine (BBR), has been firstly identified in Phellodendri Chinese Cortex (PC) by HPLC-ESI-MS/MS. Nowadays most researches on PC focus on its main components like BBR, however, the role of its naturally-occurring derivatives remains poorly defined heretofore. The present work aimed to comparatively evaluate the in vivo anti-inflammatory properties and mechanisms of DHB and BBR in three...
