Metabonomic analysis of plasma biochemical changes in pyrexia rats after treatment with Gegenqinlian decoction, aspirin and itraconazole by UHPLC-FT-ICR-MS.

Abstract

A metabonomic approach involving an ultrahigh-performance liquid chromatography combined with Fourier transform ion cyclotron resonance mass spectrometry (UHPLC-FT-ICR-MS) was used to investigate the changes in the endogenous metabolites in the plasma of rats with yeast-induced pyrexia treated with Gegenqinlian decoction (GQLD), aspirin and itraconazole. The differences in the small molecule profiles of treatment using traditional Chinese medicine, etiological treatment and symptomatic treatment were elucidated. Thirty-six plasma metabolites were identified or putatively identified, and the effects of the three medicines on the thirty-six metabolites were studied. Their metabolic pathways indicated that GQLD, aspirin and itraconazole ameliorated the rats with yeast-induced pyrexia predominantly by regulating the metabolisms of phospholipid, sphingolipid, fatty acid oxidation, fatty acid amides, amino acid and glycerolipid in vivo. The pharmacodynamics and metabonomic results showed that the three medicines exhibited the therapeutic effects on pyrexia by regulating the perturbations of multiple metabolisms. The study provided a scientific basis for an in-depth understanding of the therapeutic effects of GQLD, aspirin and itraconazole on rats with yeast-induced pyrexia.
