EVALUATION OF TRIDAX PROCUMBENS LEAF EXTRACT LOADED PVA FILM FOR WOUND HEALING APPLICATIONAbstract
Wounds are a severe health problem. The development of pharmaceutical dosage forms to ensure patient comfort and safety and optimize treatment effectiveness is of great interest to the pharmaceutical and biomaterials industries. Tridax procumbens (T. procumbens) leaf is a medicinal herb used for treating wounds since ancient times. In this work, a biomaterial film was developed by using PVA with T. procumbens leaf extract via solvent casting method to produce effective wound healing material. According to the hemolytic investigation, films made from T. procumbens leaf extract films were biocompatible. Using L929 mouse fibroblast cells, the cytotoxicity of films was examined using the MTT assay, and the same cell line was also used for a migration assay using the scratch test. The results of the in-vitro wound healing test showed that films containing 12.5 ml T. procumbens dried leaf extract are efficient in reducing the scratch open area, provoking nearly complete closure of the scratches (94%) within 24 hr without cytotoxicity. The 12.5 ml incorporated film demonstrated better wound healing potential than the 25 ml and 50 ml extract-incorporated films in fresh and dried T. procumbens leaf extract-incorporated films. The L929 mouse fibroblast cell’s increased vitality and motility indicate that the synthesized film has potential as a wound healing application.
