Outline
The paper aims to compare the protective effect of Salvia miltiorrhiza and Anemarrhena asphodeloides on AD cell model and investigate its protective mechanism by cell metabolomics platform. AD cell model was established by the abnormal phosphorylation of Tau protein in SH-SY5Y cells induced by okadaic acid. The protective effect of the extract of Salvia miltiorrhiza and Anemarrhena asphodeloides on the model was evaluated by cell proliferation-toxicity experiment. The metabolomics platform was used to study the efficacy of Salvia miltiorrhiza and Anemarrhena asphodeloides comprehensively, explore the potential biomarkers related to AD and the effect of drugs on the potential biomarkers. Salvia miltiorrhiza extract had a certain protective effect on the AD model (P < 0.05), while the Anemarrhena asphodeloides extract had no significant protective effect (P > 0.05). 45 significant differential metabolites and the related 12 metabolic pathways were identified using UHPLC-QTOF/MS platform, which were related to the AD cell model. After administration of Salvia miltiorrhiza extract, 30 different metabolites appeared callback, while after intervention of Anemarrhena asphodeloides extract, 7 metabolites appeared callback. The results showed that the extracts of Salvia miltiorrhiza and Anemarrhena asphodeloides had certain protective effects on the AD cell model with Tau protein abnormal phosphorylation, but Salvia miltiorrhiza had more extensive targets and could significantly improve the cell viability. The mechanism may be related to the regulation of the metabolic pathways of AD cell model induced by okadaic acid.
