GPP (glycoproteins extracted from Perna Viridis), was a natural product extracted from mussel. This study was designed to evaluate both the antioxidant and free radical scavenging activities and protection against H2O2-induced oxidative damage of GPP. L02 cells were exposed to 100 μM H2O2 with or without GPP at different concentrations. Cell viabilities were monitored by MTT-test, MDA production in culture medium, ROS level, SOD and GSH activities were detected. The in vitro experiments demonstrated that GPP exhibited good capacity of scavenging hydroxyl radicals and superoxide anions with activities the IC50 value of 3.38, 3.36 mg/mL respectively. GPP could significantly increase the activity of SOD and GSH, and reduce the level of MDA and ROS in the culture medium, and protect the cells against H2O2-induced stress to offer vital cytoprotection against the oxidative damage induced by H2O2 in L02 cells. These findings suggested that GPP as a natural production is a potenti al source of natural antioxidants and some extent validates its medicinal potential.
