An Extensive Analysis of Artemisia integrifolia Linn. on T2DM: Investigating Glycolipid Metabolism, Metabolic...

Type II diabetes mellitus (T2DM) is characterized by chronic glycolipid metabolic dysregulation. This study aimed to investigate the effects and mechanisms of Artemisia integrifolia Linn. (LH) as a functional food in a T2DM rat model. The UPLC-Q-TOF-MS/MS technique was used to identify the components of LH. T2DM was induced in rats via a high-fat/high-sugar diet combined with streptozotocin (STZ, 35 mg/kg, i.p.). The rats were subsequently treated with LH (90 mg/kg, 180 mg/kg) for 15 days. A total of 66 compounds were identified in both positive and negative ions. LH treatment resulted in an increase in body weight while reducing FBG levels. It also improved insulin resistance, blood lipid levels, liver pathology, function, and lipid accumulation. Furthermore, 18 metabolites and 5 metabolic pathways were identified in the liver. Mechanistically, LH may improve T2DM through modulation of the S1P and PI3K/AKT signaling pathway. Caffeic acid, coumarin, trifolin, and apigetrin were identified as the likely active components. In conclusion, LH may mitigate glycolipid metabolism disorders in T2DM rats by modulating metabolic profiling, S1P, and the PI3K/AKT signaling pathway, supporting its potential as a functional food.
