Anthocyanins attenuate alcohol-induced hepatic injury by inhibiting pro-inflammation signalling.

We assessed phytochemical components of anthocyanins from purple sweet potato (PSP) and purple potato (PP) with UPLC-MS/MS, and investigated their inhibitory effect on inflammatory response in alcoholic liver disease (ALD). Results showed that serum AST and ALT levels in PP anthocyanins (PPAs) and PSP anthocyanins (PSPAs) treatments were lower than those of alcohol-treated group. PPAs and PSPAs could inhibit mRNA expressions of inflammatory factors (TNF-α, VCAM-1, IFN-γ and CXCL-1). The mRNA levels of NF-κB, STAT, and TLR in PPAs and PSPAs treatment groups were lower than in alcohol treatment group. Our results indicate that PP and PSP are good source of anti-inflammatory anthocyanins to prevent ALD.
