Metabolomics study on the effects of Orthosiphon Stamineus Benth. on streptozotocin-induced diabetic rat model

The main purpose of this research is to study the anti-diabetic effects of Orthosiphon stamineus Benth. Extract (OSE) in different solvent polarity (ethanol, ethanol: water,methanol, methanol: water and water) in streptozotocin (STZ)-induced diabetic rats by using metabolomics approach. The rat mode...

The novelty of metabolomics approaches is their ability to give a broad overview of metabolites from complex biological samples. Interestingly, the spectroscopic data of urine STZ-diabetic rats revealed that glucose, allantoin, creatine, creatinine, and glutamate were near to normal group ranges after treatment. Furthermore, to propose the metabolism pathway affected by the OS treatment in diabetic rats, MetScape 3.0 software was used. Consequently, several metabolic pathways like carbohydrate, lipid, and amino acid metabolism have been affected during the treatment period. This study suggests that OSE of water may be beneficial in treating the hyperglycemic condition as it acts in a better way compared to glibenclamide drug.
