Objective: The objective of the present study was to determine the cellular level effect on glucose uptake and aldose reductase inhibitory activity of different extracts of traditional medicinal plant Psidium guajava.
Methods: Psidium guajava was selected and subjected for successive extraction from non-polar to polar solvents and subjected to glucose uptake and aldose reductase inhibition assay.
Results: Based on the results Psidium guajava methanolic extract (PGME) showed an enhancement in the glucose uptake and also up-regulates the gene and protein level expression of IRβ, IRS-1, PI3K and GLUT4. Wortmannin, a specific PI3K inhibitor confirms that the active PGME recruits glucose uptake through a PI3K dependent pathway. In the assay of aldose reductase inhibitory activity, the results suggested that PGME possesses a significant inhibitory effect.
Conclusion: The result obtained in the present study focuses on the anti-diabetic effect of PGME by studying cellular level glucose uptake in L6 myotubes and aldose reductase inhibitory activity.
