Biological oxidation resistance of L-ascorbic acid cellulose ester
L-ascorbic acid and sodium carboxymethylcellulose were taken as raw material to synthesize polymer material Lascorbic acid cellulose ester which had antioxidation effect. Antioxidation effect of o benzylgalloyl microcrystalline cellulose ester was appraised in vitro. The results showed that all the different concentrations L-ascorbic acid cellulose ester significantly improved GSH-Px activity of mice liver. But there was no significant difference among the low dose, middle dose and high dose group. Consequently, it can not explain that there was dose-effect relationship between them. L-ascorbic acid cellulose ester could significantly inhibit generation of lipid peroxidation product malondialdehyde(MDA) and oxidative hemolysis of erythrocyte, and there was very significantly doseresponse relationship between them. It can provide technical foundation for the further study on anti-oxidative new functional polymer materials.
