ABSTRACT
This study aimed to investigate the potential hypoglycemic mechanism of red ginseng acidic polysaccharides (RGAP) from the perspective of fatty acid (FA) regulation. A high-glucose/high-fat diet in conjunction with streptozotocin administration was employed to establish type 2 diabetes mellitus (T2DM) rat models, and their fecal FAs were detected using the liquid chromatography-mass spectrometry (LC-MS) method. RGAP treatment alleviated the polyphagia, polydipsia, weight loss, and hyperglycemia observed in T2DM rats. FA profile was disturbed by T2DM modeling, and 11 marker FAs were selected from statistical analysis, whose intensities were reversely changed by RGAP administration. Among these marker FAs, short-chain FAs were negatively correlated with the fasting blood glucose (FBG) level, while positive correlations were observed between long-chain FA and the FBG level. Combined with the metabolite-enzyme-gene network analysis, we inferred that the mechanistic mechanism RGAP on T2DM may be associated with the regulation of FA metabolism and inflammation-related signaling pathways. This study confirmed the regulatory effect of RGAP on fecal FA, which can provide a scientific basis and new ideas for developing red ginseng as a functional food for supplementary treatment of T2DM.
