چکیده

The oils extracted from seeds of two crataegus species (rosaceae),crataegus azarolus l. and crataegus monogyna jacq. collected from constantine (eastern algerian),were analyzed by gc and gc/ms. the main components of c. azarolus were tetradecamethylcycloheptasiloxane (39.43%),3,4-dihydroxytetramethylsilyl mandelic acid (19.23%),dodecamethylcyclohexasiloxane (17.14%),decamethylcyclopentasiloxane (10.57%) and 3-isopropoxy-1,1,1,7,7,7-hexamethyl-3,5,5 tris(trimethylsiloxy)tetrasiloxane (5.66%). it's the first report on c. monogyna seeds oil. the major constituents of c. monogyna seeds oil were found to be linoleic acid (44.2%),oleic acid (28.26%),oxalic acid,bis(trimethylsilyl) ester (9.74%),palmitic acid (6.56%) and tetracosamethylcyclododecasiloxane (5.04%). the antioxidant activity was investigated by the use of β-carotene bleaching method. antibacterial activity was performed according to disc diffusion and minimum inhibitory concentration (mic) methods. © 2017,university of mohammed premier oujda morocco.
