Chemical Characterization and Biological Activities of Citrus reticulata and Citrus aurantium Essential Oils Service Unavailable

This study was conducted to evaluate the chemical composition, antimicrobial and antioxidant activities of Citrus reticulata and Citrus aurantium essential oils (EOs). The chemical composition was determined by gas chromatography-mass spectrometry (GC/MS). Monoterpene hydrocarbons were found to be the main components. Antibacterial activity was evaluated against Staphylococcus aureus, Escherichia coli, Proteus vulgaris, and Pseudomonas aeruginosa. The Gram-positive bacteria Staphylococcus aureus was more sensitive than the Gram-negative bacteria. Antifungal properties were determined against Aspergillus and Penicillium species. The best results were obtained by Citrus reticulata and proved to be the most effective inhibitor of all tested fungi. In addition, the screening of the antioxidant activities showed that Citrus aurantium was more effective in scavenging DPPH radicals. A reduction in the IC۵۰ values was also noticed when the EOs were used in combination. According to these findings, the tested EOs could be used as a natural source of new compounds for the treatment of fungal and bacterial infections.This study was conducted to evaluate the chemical composition, antimicrobial and antioxidant activities of Citrus reticulata and Citrus aurantium essential oils (EOs).
