The aim of this study was to determine the chemical composition (IR), characterize minerals (ICP-OES), antioxidant activity, total phenols, inhibition of acetylcholinesterase (AChE) and antimicrobial activity of leaf extract of wild passion fruit (Passiflora foetida L.). The results obtained by Infrared of the hexane extract indicate the presence of aliphatic compounds such as fatty acids and esters, long chain alcohols and steroids.
The major minerals were: phosphorus (1093.00 mg L-1), magnesium (418.77 mg L-1), sulfur (282.56 mg L-1)and potassium (157.46 mg L-1). The total phenolic content was 16.78 mg of gallic acid equivalent 100 g-1 extract. The hexane extract showed inhibition of 17.97% for antioxidant activity. The activity on AChE was 96.46% inhibition. As for microorganisms, the extract showed inhibition on Gram-positive bacteria Bacillus cereus (77.93%), Staphylococcus aureus (88.25%), Gram-negative Citrobacter freundii (82.74%), Salmonella typhimurium (83.21%) and yeast C. albicans (53.29%).
