Abstract
AbstractPhysalis alkekengi L. var. franchetii (Mast.) Makino (PA) is a natural plant which is utilised as a traditional herbal medicine. It has properties that make it effective against inflammation and free radical damage. In the present study, the major constituents of four extraction parts of the fruits of PA (PAF) were investigated by combining ultra‐performance liquid chromatography with quadrupole time‐of‐flight mass spectrometry (UPLC‐Q‐TOF‐MS). The mice model of Alzheimer's disease (AD) induced by aluminum chloride (AlCl3) combined with D‐galactose (D‐gal) was established to comprehend the mechanism behind PAF's anti‐AD activity from both behavioural and pathological perspectives. The results showed that four extraction parts of PAF (PAFE) had favorable anti‐AD effects and the ethyl acetate (EA) group showed the best activity. UPLC‐Q‐TOF‐MS analysis identified Physalin B, Nobiletin and Caffeic acid as the main anti‐AD active constituents in EA extract. This study reveals that PAF can reduce neuroinflammatory damage by inhibiting p38 mitogen‐activated protein kinase (p38 MAPK) signaling pathway, which is the theoretical basis for clinical development and utilization of PAF in AD therapy.
