Background: Olive leaves are considered as significant sources of bioactive phenolic compounds with superior antioxidant capacity, anti-inflammatory and radical scavenging. The aim of the present study was to evaluate the effects of olive leaf extract on liver tissue following LPS administration.
Materials and Methods: 28 male Wistar rats were divided into control group, LPS, olive leaf extract 40mg/kg BW plus LPS and olive leaf extract 60mg/kg BW plus LPS groups. Control and LPS groups were treated with distilled water and olive leaf extract 40 & 60 mg/kg groups were administrated with olive leaf extract as oral for ten consecutive days. LPS and olive leaf extract groups (40 and 60 mg/kg ) received LPS (Salmonella typhosa,once 5mg/kg) in the 11th day as intraperitoneally.
Results: LPS-induced hepatotoxicity was manifested by a significant elevation in serum levels of ALT and AST enzyme activities and triglyceride concentration in comparision with the control group (P<0.001). Olive leaf extract supplementation, significantly decreased serum activity of ALT and AST enzymes and triglyceride concentration.
Conclusion: Therefore, it seems olive leaf extract containing oleuropein, is able to prevent LPS-induced hepatotoxicity in rats. |
