Algeria boasts a wealth of aromatic plants, including Origanum vulgaris, which belongs to the Lamiaceae family. Essential oils and extracts from oregano species are widely used in the pharmaceutical, cosmetic, and food industries. The present study involves a comparative analysis between spontaneously occurring and cultivated accessions in Tlemcen and Sidi Bel Abbes region (Northwest Algeria). Our study aims to conduct morphometric characterization as well as morpho-anatomical examination of the plant using five morphological traits. The obtained data underwent statistical analysis using the SPSS software. Additionally, we tested the antibacterial activity of essential oils extracted from both types of accessions. The results from multiple correspondence analysis (MCA) and hierarchical clustering analysis (HCA), along with microscopic examination, revealed a distinction between the two types of accessions. Regarding the macroscopic study, it exhibited a significant difference between the cultivated accession and the spontaneous accession. The tested bacterial strains proved to be sensitive to the essential oil extracted from the studied accessions, exhibiting antibacterial activity with an inhibition zone ranging between 9mm and 23mm.
