Metabolomic study of Gardenia jasminoside var. radicans and geniposide on degranulation model of RBL-2H3 cells / 中草药

ABSTRACT

Objective: To study the intervention effect of Gardenia jasminoside var. radicans and its main effective component of geniposide on the degranulation model of RBL-2H3 cells based on metabolomics. Methods: The changed metabolite profile of RBL-2H3 cells was detected by UPLC-QTOF-MS; PCA (principal component analysis) and OPLS-DA (orthogonal partial least squares discriminant analysis) in SIMCA software were used to select the potential biomarkers. Meanwhile, the clustering and heat map analysis for those potential biomarker levels were carried out by MEV software. Result: A total of 54 and 46 relevant biomarkers of G. jasminoside var. radicans and geniposide were selected, of which 31 biomarkers enriched in five disturbed metabolite pathways, including glycine, aspartic acid and glutamate metabolism, glutathione metabolism, histamine metabolism, energy metabolism, and nicotinamide metabolism pathways. Conclusion: G. jasminoside var. radicans and geniposide exerts the inhibitory effect on the degranulation model of RBL-2H3 cells by regulating histamine metabolism, oxidative stress and energy metabolism, and geniposide was one of the main efficacious substance basis of G. jasminoside var. radicans.
