Antioxidant Activity An investigation was carried out in order to estimate the biochemical changes occurring in bitter orange (Citrus aurantium L.) leaves in response to melatonin (MEL), gibberellic acid (GA) and salicylic acid (SA) treatments. It could be concluded that 15 mM MEL, 1.44 mM GA and 1 mM SA increased the total phenolic and flavonoid content of bitter orange leaves, as well as their antioxidant activity. (Sarrou et al., 2015) Antibacterial The results of the micro-dilution assay presented petitgrain oils have the most antibacterial and antifungal propertyIn conclusion, demonstrating that essential oils of C. aurantium leaf have antimicrobial activities. The high in vitro antimicrobial activity of bitter orange leaf oil could be attributed to the presence of high amounts of oxygenated monoterpenes such as linalool, alpha terpineol, and linalyl acetate. Statistics showed it is effective against Staphylococcus aureus (cause a range of illnesses: from minor skin infections, such as pimples, impetigo, boils, cellulitis, folliculitis, carbuncles, scalded skin syndrome, and abscesses, to life-threatening diseases such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome, bacteremia, and sepsis), Streptococcus Faecalis (cause a variety of infections, including endocarditis, urinary tract infections, prostatitis, intra-abdominal infection, cellulitis, and wound infection as well as concurrent bacteremia) and Salmonella Typhi (bacteria that infect the intestinal tract and the blood, causes typhoid fever).
