Abstract: Objective To examine the mutagenicity and antioxidant activity of Proanthocyanidin( PC). Methods Three mutagenicity tests including Ames test,bone marrow micronucleus test and sperm malformation test in mice were conducted. According to the level of erythrocyte MDA,11-month-old rats were randomly divided into five groups including blank control,solvent control and 41. 67,83. 33,250. 0 mg/kg test groups. The content of erythrocyte MDA,SOD and GSH-PX activity of each dosage group were then observed after administration of PC to test the antioxidant activity. Results In all three mutagenicity tests,no mutagenic effect was observed in any PC - treated group. Compared with two control groups,the content of erythrocyte MDA was significantly decreased in 83. 33 and 250. 0 mg/kg groups(both P<0. 05) and GSH-Px activity was significantly increased in 250 mg/kg group(P<0. 05). Conclusion PC had no mutagenic effect but showed antioxidant activity under our experimental conditions.
