STUDY OF THE INDIVIDUALITY EFFECT ON THE CHEMICAL COMPOSITION AND ANTIBACTERIAL ACTIVITY OF ESSENTIAL OILS OF ROSMARINUS OFFICINALIS VAR. PROSTRATUS GROWN IN THE MOROCCAN EXPERIMENTAL GARDEN

The present article has been devoted to the performance identification and comparison of the chemical composition and antibacterial properties of the essential oil extracted from seven Rosemary officinalis var. prostratus. The individual’s I5 and I7 have higher performance 1.79% and 1.93% respectively. The antibacterial activity study results indicated that the individual 5 and 7 have a much higher antibacterial effect than the other individuals as regards the three tested strains. GC and GC/MS chemical analysis identified that more than 97.21% of total volatile products (97.21% and 98.43% for I5 and I7 respectively). Both individuals I5 and I7 may be selected for future vegetative propagation to get clones having the capacity to provide a standard production. This production will provide an essential oil with significant activity as regards the tested strains. This could help resolve bacterial infections problem.
