The essential oils and defatted ethanolic extracts obtained from Cupressus sempervirens L. leaves collected from two geographically distinct regions in Lebanon (Beit El-Dein: mountain and Jbeil: sea-side) were analyzed for their chemical composition using GC/MS and phytochemical screening. These were then tested for their in-vitro antibacterial and anti-oxidant potentials. Many terpenoids have been detected in the essential oils at various percentages with α-pinene and δ-3-carene being the major constituents. Regarding the anti-oxidant potential study, the ethanolic extracts were able to effectively reduce DPPH which was strongly correlated with the high phenol and flavonoid content of these extracts. Regarding the anti-bacterial activity, essential oils exhibited a stronger potential mainly towards Gram-positive bacteria compared to the ethanolic extracts as shown by the disc-diffusion assay and minimal inhibitory concentration assay. The results obtained from this study reveal that the extracts of Lebanese Cypress leaves may be used as a good source of natural food preservatives and as drugs for various ailments.
