Elderberry (EDB) Sambucus nigra L. is one of the oldest medicinal plants which is useful for therapeutic and nutritional purposes due to a large amount of biologically active constituents, including compounds with a high antioxidant capacity. The present study focused on the antioxidant potential of the colon-available EDB fruit extract, derived from the artificial gastrointestinal tract, with regard to human colonic mucosa cells cultured in vitro. Despite the significant loss of EDB bioactive compounds due to the digestion process, the colon-digested extract was able to reduce the excessive intracellular ROS production (22%) and oxidative DNA damage (46%) in the colon cells at a dose of 1mg of freeze-dried EDB powder/ml. Moreover, the colon-digested EDB extract inhibited oxidant-induced mutagenicity (26%) in the Salmonella typhimurium TA102 strain, as determined by the Ames test. In conclusion, the current in vitro study confirmed that the fruits of S. nigra are capable of protecting colonic cells against the detrimental effects of oxidative stress.
