Despite advances in wound treatment, wound-associated infections and delayed healing still remains an 'unmet clinical need'. The present treatment modalities include topical application of ointments and perhaps it may better be substituted by phytochemical incorporated nanofibers which increases wound-healing efficiency and reduce risk of infections. Hence, the aim of this study was to synthesise Areca catechu –incorporated polycaprolactone scaffolds for wound-healing applications. In this study, the tender nut of Areca catechu plant was collected and extracted with ethanol using the maceration technique. The presence of various active phytochemical constituents of ethanolic fraction of Areca catechu like phenol, flavonoid, tannin and alkaloid were identified qualitatively and estimated quantitatively. Areca catechu incorporated 10%w/w polycaprolactone scaffolds were fabricated by electrospinning technique and characterised physico-chemically by Fourier-transform infrared spectroscopy and scanning electron microscope analysis. In vitro cytotoxicity analysis was evaluated with L929 fibroblasts and in vivo wound-healing studies using rat models for both polycaprolactone and Areca catechu –incorporated polycaprolactone scaffolds. Extract of Areca catechu exhibited antioxidant properties and antibacterial activity against Staphylococcus aureus and Psuedomonus aer u ginosa. Scanning electron microscope image revealed the nanofibrous structural morphology of Areca catechu –incorporated polycaprolactone and polycaprolactone with average diameter of 350 and 399 nm, respectively. The characteristic peak of Fourier-transform infrared spectroscopy depicted the presence of biomolecules and detection of functional groups confirming the incorporation of Areca catechu into the polycaprolactone scaffold. Furthermore, cells were cytocompatible with 85% viability over Areca catechu –incorporated polycaprolactone scaffolds, and wounds treated with Areca catechu –incorporated polycaprolactone healed faster with a significant difference in the wound area than polycaprolactone controls. The phytochemical-incorporated polycaprolactone scaffolds with antioxidant, antimicrobial, biocompatible and wound-healing properties is proposed to be an indigenous approach towards wound care management globally and seems to be better and cost-effective wound dressings.
