Determining the antioxidant capacity of the liver of rainbow trout exposed to yersiniosis vaccine

Objective: To date, there are no studies about the antioxidant capacity of liver in fish exposed to yersiniosis vaccine. The aim of the study was to compare the antioxidant capacity of the liver of rainbow trout exposed to the yersiniosis vaccine and non-exposed fish. Methods: The amounts of carotenoids, cupric assay, and lipid peroxidation levels were determined. The samples were normalized by Bradford test. Results: Walnut brown seed coat at ۱% was effective as BHT in inhibition of lipid peroxidation. This extract presented the highest Vitamin E content (۱.۴± ۰.۰۴۲ mg/g). DPPH assay showed the extract have high radical scavenging ability. Conclusions: The results of this study indicate walnut brown seed coat possesses strong antioxidative properties in vitro
