Poster summary

The effect of Thaumatococcus daniellii seed ethanol extract on oxidative stress parameters in male Wistar rats was assessed using standard methods. The extract decreased hepatic lipid peroxidation while superoxide dismutase activity and glutathione level was increased in the experimental animals. Histological analyses of the liver showed no significant abnormality indicating little or no toxicity to the hepatocytes. Ethanolic extract of Thaumatococcus daniellii fruit pulp showed antioxidant properties, comparable to commercial vitamin C supplement. Further work is needed to characterize the bioactive compounds and their mechanisms of action.
