The chemical compositions and the antioxidant and antimicrobial activities of the essential oil of Rosemary leaves from eastern Morocco

The essential oils compositions of rosmarinus. tournefortii wild plant,rosmarinus. tournefortii domesticated plant,and rosmarinus officinalis. l wild plant growing in different bio climates from eastern morocco,was determined by gc-fid and gc-ms. oils were assessed for their antimicrobial and antioxidant activities. a variation of chemical compositions attributed to varieties rather than to bio climates was revealed. α-pinene (0.637%; 44.22%; 5.74%),camphene (11.62%; 6.52%; 2.21%),ß-pinene (14.72%; 1.14%; 3.71%),1,8-cineole (10.1%; not identifying; 56.51%) and camphor (39.27%; 7.64%; 13.56%) were identified as the main constituents of r. tournefortii wild plant,r. tournefortii domesticated plant,and r. officinalis. l wild plant respectively. this study is based on the determination of the diameter of inhibition to moderate antimicrobial and antioxidant activities of oils revealed to be against eight bacteria tested. this was determined by 1,1-diphenyl-1-picrylhydrazyl (dpph) assay. the highest antimicrobial and antioxidant activities were found in oils from rosmarinus. tournefortii domesticated plant.
