Hawthorn flavonoid ameliorates cognitive deficit in mice with Alzheimer's disease by increasing the levels of <i>Bifidobacteriales</i> in gut microbiota and docosapentaenoic acid in serum metabolites

Abstract

, as well as increasing the levels of docosapentaenoic acid (DPA), sphingolipid (SM), and phosphatidylcholine (PC). Notably, a positive correlation between DPA and Bifidobacterium was observed for the first time. Therefore, HF may serve as a promising dietary supplement for improving the symptoms of Alzheimer's disease.
