بررسي فعاليت آنتي اكسيداني برگ دو رقم زيتون (ميشن و كنسرواليا)

(The antioxidant activity of two varieties of olive leaves (Mission and Conservalia

مصرف تركيبات آنتي اكسيداني مشتق از گياهان، باعث كاهش شيوع بسياري از بيماريهاي مزمن ميشود. هدف از اين مطالعه، بررسي خواص آنتي اكسيداني عصاره هاي. برگ دو رقم زيتون (ميشن و كنسرواليا)است. ابتدا عصاره ها اتري و پنتاني از برگهاي دو رقم زيتون تهيه شدو سپس بااستفاده از توان حذف راديكالهاي آزاد به روش 2 و 2 ديفنيل-1-پيكريل هيدرازيل (DPPH) ميزان اثر آنتي اكسيداني اندازه گيري شد. نتايج نشان داد كه نمونه برگ كنسرواليا درصد عصاره گيري، درصد مهار و خواص آنتي اكسيداني بالاتري نسبت به نمونه برگ ميشن با حلال هاي يكسان دارد.

Consumption of antioxidant compounds derived from plants, reduces the incidence of many chronic diseases. The aim of this study was to evaluate the antioxidant properties of extracts of leaves of two varieties of olive (Mission and Conservalia). The ether and pentane extracts prepared from leaves of olive varieties and then using 2, 2-Diphenyl-1-picryl-hydrazyl (DPPH) the power of antioxidant effects was measured. The results showed that Conservalia leaf extract has more yield, higher inhibition percent and more antioxidant properties.
