Abbreviations: BSTSF: Bushen Tiansui Formula; AD: Alzheimer's disease; Rt (min): retention time; VIP: variable importance; FC: fold change. Fold change was calculated as average relative quantitation obtained from group BSTSF/group AD, and a value less than 1 indicates a decrease in the metabolites of group BSTSF. The levels of potential biomarkers were labeled with “↓” (downregulated) and “↑” (upregulated) (^∗p < 0.05). ^aChange trend compared with the sham group. ^bChange trend compared with the AD group.
