**4.2 Effect on memory**

The essential oil of *P. lenticus* attenuated memory dysfunction in rats. *P. lentiscus* oil (PLo) at a dose of 3.3 mL/kg for 15 days reversed LPS-induced memory deficits in rats. Besides, the increased acetylcholinesterase activity in brain structures of LPS-treated rats was reduced by PLo. Additionally, PLo significantly attenuated the increased oxidative stress in the brain of LPS-treated rats [60]. The chemical induced memory impairment was regulated with *P. vera* fruit [61].
