Oligosaccharides from black ginseng innovatively prepared by low‐temperature steam‐heating process ameliorate cognitive impairment in Alzheimer's disease mice via the Keap‐1/Nrf2 pathway

Our results showed for the first time a clear role for OSBG in improving scopolamine-induced memory impairment by inhibiting cholinergic dysfunction in a tissue-dependent manner. Additionally, OSBG administration relieved oxidative stress by activating the Keap-1/Nrf2 pathway and modulating the gut microbiota. Collectively, OSBG may be a promising target for neuroprotective antioxidants for improving memory and cognition in Alzheimer's disease patients. © 2024 Society of Chemical Industry.
