Metabolomics Revealed the Effects of Momordica charantia L. Saponins on Diabetic Hyperglycemia and Wound Healing in Mice

Momordica charantia L. saponins (MCS) may promote wound-healing properties but the underlying mechanisms are unclear. This study aimed to examine the effects and mechanisms of MCS on diabetic wounds. The results have shown that higher MCS intake lowered fasting blood glucose levels, serum lipids, and lipopolysaccharides in diabetic mice. MCS-treated diabetic mice exhibited faster wound healing than the diabetic control groups. After three days, the diabetic control groups exhibited a wound area reduction of only 19.3%, while a 39.75% reduction was observed following high-dose MCS treatment. Five potential biomarkers were screened in the metabolomics study. The results revealed that MCS mainly regulated glycerophospholipid metabolism, fructose and mannose metabolism, steroid hormone biosynthesis, pyrimidine metabolism, and the Krebs cycle, thus affecting wound healing. Overall, MCS could not only exert a hypoglycemic effect but also promote diabetic wound healing, making it a potential treatment option for diabetes-related wounds.
