In this study, the protective effects of 30%, 50%, and 70% ethanol fractions of IS on rats with THBSS were evaluated by observing myocardial pathology, analyzing blood rheology and blood routine indices, and the general conditions of the rats. Comprehensive metabolomic analysis of plasma and myocardium samples was conducted using ultra-high-performance liquid chromatography linear ion trap quadrupole orbitrap mass spectrometry (UHPLC-LTQ-Orbitrap MS/MS). The results showed that IS-30% had a significant protective effect on rats with THBSS, and it could play a protective role by modulating 35 differential metabolites associated with key metabolic pathways, including glycerophospholipid metabolism, sphingosine metabolism, alpha-linolenic acid metabolism, and nicotinate and nicotinamide metabolism. Analysis of different metabolites and pathways showed that they are closely associated with inflammatory responses; therefore, it is hypothesized that IS-30% may protect against THBSS by exerting an anti-inflammatory effect.
