Abstract

Objective: Aim of the present study was the development, optimization and evaluation of myricetin-loaded nanoemulsion gel for wound healing.

Methods: Myricetin nanoemulsion was prepared by selecting Peanut oil as oil (wt %), Tween 20 and Polyethylene glycol 400 as surfactant and cosurfactant (S_mix) and aqueous phase water. Performance of nanoemulsion gel was evaluated by wound healing activity tested against wound contraction, hydroxyproline content, protein content and antioxidant assay.

Results: The optimized nanoemulsion (NEF1) exhibited appreciable stability concerning droplet size and PDI when stored at 5 ᵒC, 25 ᵒC and 40ᵒC up to three months. Morphological characterization by TEM indicated a spherical shape. Wound healing effect was observed through a significant (p<0.5) increase in hydroxyproline content, protein content and antioxidant status in wound tissue. The level of superoxide dismutase (SOD) and catalase were found to increase significantly in wound tissue after treatment with Myricetin loaded nanoemulsion (MYCT-NE) gel, as well as results were comparable to Betadine cream.

Conclusion: In conclusion, MYCT-NE gel was found potent wound healing effect through the reduction of oxidative stress and epithelialization of tissue.
