Wound healing potential of curcumin cross-linked chitosan/ polyvinyl alcohol

This study focusses on antibacterial properties and wound healing potential of curcumin cross-linked with chitosan-PVA membranes. The crude curcumin was extracted from the rhizome of (Curcumin longa) and chitosan-PVA 80 was also prepared separately. The synergistic potential 10, 20 and 30 mg of curcumin alone and in combination with chitosan-PVA was determined. The antibacterial, scavenging potential of free radical, total phenolic and total flavonoids contents were documented through spectrophotometric methods. Finally, the wound healing potential was tested on experimental animal (rabbits). Rabbits were divided into different groups; untreated (control), treated with 10, 20 and 30 mg of curcumin and its combination with chitosanPVA80. Chitosan-PVA exhibited significant antibacterial property against bacterial pathogens. Wound healing trials on 2nd degree burns showed chitosan as substantial wound healing agent for wound bandages. Results have shown that chitosan wound gauzes augmented the granule and fibrous connective tissues formation. (C) 2019 Elsevier B.V. All rights reserved.
