Abstrait
Gardenia jasminoides (G. jasminoides) fruits, as a kind of traditional Chinese medicines (TCMs), have shown prospects in the prevention of diabetes and its complications. However, due to its chemical diversity and multiple biological targets, the effective mechanism remains largely unknown. In this study, mass spectrometry-based metabolomics was applied to uncover the underlying therapeutic mechanism of G. jasminoides on type 2 diabetes (T2D) and its clinical complications. We established a T2D rat model using high-fat diet and identified 45 urinary endogenous metabolites as potential diagnostic biomarkers for T2D rats. After treatment with G. jasminoides, pathologic symptoms of T2D rat were significantly improved and some of the diagnostic biomarkers were significantly regulated. Bioinformatics analysis demonstrated that these therapeutic biomarkers were involved in bile acid biosynthesis, amino acid metabolism, vitamin B metabolism, taurine metabolism, etc., which indicated potential therapeutic mechanisms of G. jasminoides on T2D and its complications.
