Objective: To study antioxidant activity of the different part of Elaeagnus bockii in vitro and in vivo
and evaluate the value of development and utilization of aboveground parts of elaeagnus and anti-atherogenic effects. Method: Evaluation of its antioxidant activity in vitro were based on effect of copper ion-induced low density lipoprotein(LDL)oxidation and· OH and O2 . scavenging at low
middle and high concentration(5
10
20 g· L-1). The model KM mice were induced by injecting subcutaneous 5% D-galactose for 8 weeks. Intragastric administration for 14 days and then the orbital blood was taken to test total antioxidant capacity (TAC)
superoxide dismutase(SOD)
glutathione peroxidase(GPX) antioxidant enzymes activities and malonyldialdehyde(MDA) content in serum(2
5
10 g· kg-1). Result: The rate of free radical scavenging for O2 . at different concentration of Root and rhizome(UP) part were (58.26±6.14)%
(68.21±3.47)%
(74.67±4.10)%
the radical scavenging for· OH were(48.24±6.24)%
(78.21±7.24)%
(90.17±6.58)%. The free radical scavenging rate of the ground part was higher than that of underground parts. Extracts from different parts significantly increased oxidation of delay time(Lag time) and the maximum rate of oxidation time (Tmax). The result was consistent with reduced MDA formation induced by copper ion. Serum TAC
SOD
GPX activity of antioxidant enzymes could be increased obviously
and decreased the content of MDA in serum of mice. Conclusion: Different part of E. bockii has good antioxidant activities in vitro and in vivo
significantly increase LDL and serum antioxidant capacity. Antioxidant activity of elaeagnus on aerial parts is significantly superior to the underground parts
which can be developed from above ground parts of elaeagnus for its great development value.
