The protective effect of Moringa oleifera leaf extract on liver damage in mice infected with Plasmodium berghei ANKA

Objective:To investigate the protective effect of Moringa oleifera leaf extract on liver damage in mice infected with Plasmodium berghei ANKA(P.berghei)Methods:For extraction of Moringa oleifera(M.oleifera)leaves,microwave with hot water method was used and acute toxicity study was then be done.Standard Peters’test was carried out to test the efficacy of M.oleifera extract in vivo.The ICR mice were inoculated with 1×10^(7)red blood cells infected with P.berghei strain by intraperitoneal injection.They were subsequently given with 100,500 and 1000 mg/kg of this extract by intragastric route once a day for 4 consecutive days.Parasitemia was estimated using microscopy and levels of aspartate aminotransferase,alanine aminotransferase and albumin were also measured.Results:The M.oleifera leaf extract showed the protective activity on liver damage in mice infected with P.berghei in a dose-dependent fashion.It can be indicated by normal levels of aspartate aminotransferase,alanine aminotransferase and albumin in mice treated with extract.The 1000 mg/kg of extract was observed to present the highest activity.Interestingly,the dosedependent antimalarial activity was also found in the mice treated with extract.Conclusions:The M.oleifera leaf extract presented protective effect on liver damage in mice infected with P.berghei.
