The biological properties of plant oils are improved by their conversion to nanoemulsions (NEs). This study evaluated the antimicrobial, antioxidant, and anti-hemolytic efficacy of coconut and salad rocket oils and their NEs. The result of the gas chromatography-mass spectroscopy analysis of the oils showed varied constituents such as palmitic acid, trimethylsilyl ester; 2,3-bis(acetyloxy)propyl laurate in salad rocket oil, 2-lauro-1,3-didecoin, n-butyl laurate; laurin, tri-; laurin in coconut oil. NEs diameter of salad rocket and coconut oils was 24.6 and 29.2 nm, respectively. More inhibitory activity of NEs compared with non-NEs form against Bacillus cereus, Staphylococcus aureus, Escherichia coli, Salmonella typhi, Candida albicans, and Aspergillus flavus was detected. Coconut oil and its NEs caused 14.3% (anti-hemolysis 85.7%) and 22% hemolysis (anti-hemolysis 78%), respectively. Salad rocket oil and its NEs caused hemolysis 3.4% and 20.9%, respectively at 1000 µg/mL. Antioxidant activity of salad rocket and coconut oil reflected more IC50 (39.3 and 109.4 µg/mL) than its NEs (35.8 and 80.5 µg/mL), respectively. Molecular docking of trimethylsilyl ester and 2-lauro-1,3-didecoin against S. aureus (PDB=7BGE) and C. albicans protein (PDB=3DRA) revealed optimal binding mode that had the most energy interaction with the binding sites
