Abstract The present study was aimed at conducting phytochemical analysis and evaluating the in vitro antifungal and antioxidant activities of the essential oil obtained from the fruits of J. oxycedrus L. Hydro-distillation was used to extract the essential oil from the fruits of Juniper oxycedrus. The essential oil was analyzed using gas chromatography with a flame ionization detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC/MS). The antioxidant activity of the essential oil against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals was determined in vitro using varying concentrations of the essential oil and vitamin C as a standard antioxidant compound. A disc diffusion test was employed to evaluate the antifungal activity of the essential oil against two test fungal strains, Penicillium citrinum, and Aspergillus niger. The results revealed that 49 constituents were identified in fruit oil, representing 91.56% of the total oil and the yield was 1.58%. Juniper fruit oil was characterized by having high contents of ß-pinene (42.04%), followed by limonene (15.45%), sabinene (9.52%), α-pinene (5.21%), (E)-caryophyllene (3.77%), ρ-cymene (1.56%), caryophyllene oxide (2.02%), and myrcene (1.02%). The radical scavenging activity (% inhibition) of the essential oil was highest (81.87± 2.83%) at a concentration of 200 µg/mL. The essential oil of J. oxycedrus exhibited antifungal activity against A. niger and P. citrinum with minimum inhibitory concentration values (MIC) ranging from 2.89 to 85.01 µl/mL. The findings of the study reveal that the antioxidant and antifungal properties of J. oxycedrus essential oil and their chemical composition are significantly correlated
