In connection to search for safe and alternative plant-based drugs, the wound healing mechanisms of an Indian ethnomedicine Couroupita guianensis fruit pulp was analyzed in this project work. Gas chromatography coupled with mass spectrometer (GC-MS) analysis revealed the existence of phytochemicals such as 2-furoic acid, 2,4-heptadienal, pyrazole and 8-hydroxyquinoline in the methanol extract. Methanol extract of C. guianensis exhibited remarkable radical scavenging activity against 2, 2-diphenyl-1-picrylhydrazyl (DPPH) (89.88%), superoxide (91.51%), hydrogen peroxide (24.25%) and hydroxyl radicals (73.62%). Further, it showed remarkable anti-inflammatory (24.09-62.16%) and anti-bacterial activity (zone of inhibition, ZOI: 13.00 mm, minimum inhibitory concentration, MIC: 6.25 mg/mL and minimum bactericidal concentration, MBC: 12.51 mg/mL) and also controlled the growth rate of methicillin resistant Staphylococcus aureus (MRSA) within 30 min of treatment. The angiogenic potential of C. guianensis was proved in chick chorioallantoic membrane (CAM) model and it does not exhibit any toxicity in peripheral blood monocyte cells (PBMC) model.
