Chemical profiles were characterized by UHPLC-Q-TOF-MS. Anti-Parkinsonian effects were evaluated in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD mice through behavioral tests (pole, rotarod, open-field, gait, and Morris water maze), biochemical analyses (tyrosine hydroxylase, \u03b1-synuclein, and inflammatory markers), and histological examinations. Gut microbiota composition was analyzed via 16S rRNA gene sequencing to identify modulation patterns associated with health outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Chemical profiling revealed substantial compositional differences among extracts depending on geographical origin and extraction method. All OJ extracts significantly ameliorated MPTP-induced motor deficits, anxiety-like behaviors, dopaminergic neuron loss, and neuroinflammation, indicating broadly comparable anti-Parkinsonian effects. Notably, water extract of OJ from Sichuan (COJ_W) was the only group that significantly improved cognitive performance compared with the MPTP group. Concurrently, differential gut microbiota modulation patterns were observed across treatment groups.
