Abstract:

This study was designed to evaluate the radioprotective effect of phenolics extracted from the fruits of Malus baccata (Linn.) Borkh. (MBP-3b) against damage induced by (60)Coγ-irradiation in vivo. MBP-3b could significantly improve the activity of endogenous antioxidant enzymes and the T-AOC, as well as reduce the MDA level in the liver and kidneys of irradiated mice. In addition, pretreatment with MBP-3b at a dose of 150 mg per kg bw could significantly enhance immunomodulation activity by promoting the proliferation of spenocytes and monocyte phagocytosis. The administration of MBP-3b prevented the decline induced by radiation of haematological parameters (WBC, RBC, PLT and HGB). Furthermore, MBP-3b could protect spenocytes from radiation-induced damage by inhibiting cell apoptosis. The results indicated that MBP-3b possesses strong whole body radioprotective and immunomodulatory activities. The main constituents of MBP-3b were tentatively identified as delphinidin-3,5-diglucoside, cyanidin-3-glucoside, chlorogenic acid, proanthocyanidin C1, quercetin-3-galactoside, quercetin-3-glucoside, quercetin-3-xyloside/arabinoside, phloretin-2-xyloseglucoside, quercetin-3-rhamnoside and phlorizin. MBP-3b could be used as a probable radioprotector against gamma radiation induced oxidative damage.
