Apart from being well known to the world as herb-based sweetening additive,Stevia rebaudiana (S. rebaudiana)and its phenolic compounds are considered as a natural antidiabetic alternative to replace synthetic drugs that possess numbers of side effects. Therefore, this study was aimed to evaluate the solvent effects on the extraction of phenolic compounds and steviol glycoside identification associated with antidiabetic potential of the extracts.Total phenolic (TPC) and flavonoid (TFC) content of the extracts were quantified, while the antidiabetic activity of the extracts was determined by α-amylase and α-glucosidase inhibitory assay. As a matter of interest, TFC was found to be present at the highest concentration in ethanol extract (10.91 mg QE/g), while the presence of TPC showed no significant difference between water extract (6.65 mg GAE/g) and other organic solvents. HPL Canalysis showed the abundant presence of steviol glycoside in the water extract, the principal compound suggested for treating diabetes. Furthermore, GC-MS analysis has shown the major compounds of 1-hepta-triacotanol, duvatrienediol, dihydroxanthin,β-amyrin, lupenone, phytol,γ-sitosterol, agatholic acid and fattyacids were present. In relation to the antidiabetic potential, the effects of the extracts in inhibitingα-amylase andα-glucosidase activity were investigated in vitro. Interestingly, among all S. rebaudiana extracts, water extract exhibited the most significantα-amylase inhibitory activity with IC50= 8.63μg/ml, comparable to the synthetic drug, acarbose IC50= 13.73μg/ml. These findings demonstrated that phenolic recovery was highly dependent on extraction solvent and the promising water extract as the bestα-amylase inhibitory potential with greatest steviol glycoside recovery.
