摘要：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%), decamethyl-cyclopentasiloxane (10.57%) and 3-isopropoxy-1,1,1,7,7,7-hexamethyl-3,5,5 tris(tri-methylsiloxy)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.
