Product Description
Procyanidin B2 is a phenol and a dimer of (–)-epicatechin (Item No. ) that has been found in apple pomace and has diverse biological activities.,,, It inhibits MCF-7 breast cancer cell proliferation (IC50 = 19.2 µM). Procyanidin B2 scavenges 2,2-diphenyl-1-picrylhydrazyl (DPPH; Item No. ) and superoxide anion radicals in cell-free assays. It inhibits LDL oxidation in vitro by 79.5 and 98% when used at concentrations of 5 and 10 µM, respectively. Procyanidin B2 (100 mg/kg) prevents carbon tetrachloride-induced increases in serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities and hepatic injury in mice.
