A. F. | Al-Saadi A.H. | Al-Saadi M.H. | Hamad Wessal H.
Sage leaves were successively extracted with water, chloroform: methanol (2:1, v/v), n- hexane, benzene, diethyl ether, chloroform, chloroform: methanol (8:2, v/v) and dichloromethan. Antioxidant activities were detected using two methods :1. The carotene spray method and 2.Measuring the coupled oxidation of β–carotene and linoleic acid. Generally, all extracts had antioxidant activities when tested by the first method. By means of the second method, the extracts of water, diethyl ether and chloroform : methanol( 8:2, v/v ) showed the greatest antixidant activities , followed by the extracts of organic and aqueous phases ( which were extracted with chloroform: methanol, 2:1, v/v), dichloromethan and chloroform, while the n- hexane and benzene extracts showed low activities.
