Lipid Peroxidation and Total Antioxidant Capacity in the Muscle Tissue of Atlantic Sturgeon (Acipenser oxyrinchus oxyrinchus Mitchill) after In Vitro Treatment by Extracts Derived from Various Species of Dracaena Genus (Asparagaceae Juss.)

Water extracts from selected Dracaena plants cultivated in greenhouse conditions were evaluated for antioxidant properties by vitro methods using the muscle tissue of Atlantic sturgeon (Acipenser oxyrinchus Mitchill). The level 2-thiobarbituric acid reactive substances (TBARS) and total capacity (TAC) after treatment derived leaves (in final concentration 10 mg.mL-1) assessed. When was incubated with leaf various species belonging to genus, TBARS significantly increased sixteen studied. Moreover, all (except D. singularis extract) increase formation extracts-treated tissue, these results statistically significant. Treatment genus revealed also TAC level. homogenates fifteen hyacinthoides roxburghiana extracts) induced sturgeon, increases It can be supposed that secondary plant metabolites, i.e. polyphenolic compounds, alkaloids, flavonoids, saponins, glycosides, terpenoids, tannins, etc., may contribute their activity. Further detailed studies on effect long time intervals, antioxidant, molecular aspects are necessary understand mechanism action other fish animals.
