The Antioxidant and Antihaemolytic Activities and the Polyphenolic Contents of Some Plants Seeds Extracts

Results of the this study which were carried out on yhe ethanol and acetone extracts of Prunus armeniaca, Cerasus vulgare, Nespole, Opuntia ficus-indica, Cucumis melo, and Vitis vinifera proved that theses extracts contain bioctive substances such as polyohenols and flavonids. The UV-VIS spectropgotometric assays showed that the extracted materials posses strong band in the range between 250-300 nm which confirm the presence of polyphenols and flavonoids. The concentration of these materials were different depending on the type pf plant seeds and the solvents used for extraction. The antioxidant and antihaemolytic activities of the extracts were determined by 1, 1-dipheny1-2picry1-hydeazy1 (DPPH) method, and red blood cells (RBCs) haemolysis test. Results of these extracts showed remarkable antioxidant activities depending on the origin of plant extracts. (Author's) 23 refs., 4 Tabs., 1fig
