This study analyzed the polyphenolic compounds found in Newfoundland berries, including blueberries, lingonberries, and black currants. Using HPLC and MS detection, the researchers identified 21 phenolic compounds in the three species. They also tested the lingonberry extract and found it provided complete protection from cell death in an in vitro model of cell injury. These findings suggest that these berries could be used as dietary supplements and have potential for protecting the nervous system from traumatic injuries.
