Flavonoids from Shiliangcha (Chimonanthus salicifolius) Alleviate Brain Aging in d-Galactose-Induced Senescent Mice through Gut Microbiota

, promoting the production of short-chain fatty acids (SCFAs). Therefore, this study suggested that CsFE has the potential to resist brain aging through intervention of the microbiota-gut-brain axis (GBA), which provides a theoretical basis for the development of natural drugs and dietary supplements for antiaging.
