Ampelopsin (APS) is the main bioactive component from Ampelopsis grossedentata and has anti-inflammatory properties. We hypothesize that it could reduce the acute phase response (APR) and help to maintain balance between inflammation-mediated oxidative damage and APS-induced protective mechanisms in liver. In the present study, APS possessed strong DPPH, ABTS, H2O2 and O2 radical scavenging activities in different in vitro antioxidant assays. Further study demonstrated that APS alleviated APR as reflected in the changes in the whole body metabolic rate, physical conditions, and production of cytokines in LPS-treated piglets. Moreover, APS has the potential to prevent Akt-mediated activation of NF-κB and decreased the levels of STAT3 in inflammation. The administration of APS ameliorated mitochondrial dysfunction and moderated the involvement of Ref-1 and Nrf2 in the attenuation in LPS-induced APR. The present results suggest that the APS attenuate LPS induced inflammation and oxidative stress in liver of piglets.
