: Antioxidant, Antibacterial, and Antifungal Properties of Chemically Profiled Essential Oils: An Approach against Nosocomial Infections.

is a medicinal plant in the family Convolvulaceae, which is used in traditional phytotherapy. The objective of this work was conducted to valorize essential oils of (EOCA) in terms of chemical composition, antioxidant, and antibacterial properties. To achieve this objective, the chemical composition was performed by the use of GC-SM. Antioxidant power was effectuated by the use of DPPH, FRAP, and TAC assays. Evaluation of the antimicrobial power was conducted against clinically important pathogenic bacteria ( and ) and fungi ( and ) by the use of disc diffusion and minimum inhibitory concentrations (MICs) assays. The results showed that the yield of recovered EOs from was 0.34% of the total mass of leaves and mainly was rich in cuprenne (34%), thymol (20%), himachalene (16%), and longifolene (10%). Notably, EOCA exhibited important antioxidant effects, wherein IC (DPPH) and EC (FRAP) were determined to be 30 µg/mL and 120 µg/mL, respectively, while the total antioxidant power was determined to be 508.0 ± 6.0 µg EAA/mg. An important antibacterial effect was noted for EOCA as an excellent inhibition zone was recorded against all bacterial strains, particularly and with 14.27 ± 0.42 and 21.35 ± 0.76 mm, respectively. Similarly, MICs of and were 21.35 ± 0.76 mm and 28.62 ± 1.65 µg/mL, respectively. Noticeably, important antifungal activity was shown by EOCA against all fungal strains wherein the inhibition zone diameters against all fungal species ranged from 19.44 ± 1.10 to 20.41 ± 1.81 mm. Notably, MICs of EOCA against and were 18.65 ± 0.94 and 19.38 ± 0.58 g/mL, respectively. The outcome of the present work showed that EOs from can be used to conceptualize drugs to manage diseases relative to free radicals and infections.
