To investigate the potential of hydroethanolic extract of Moringa oleifera (MOHE) against 7, 12-dimethylbenz [a] anthracene (DMBA)-induced toxicity in male Swiss albino mice.


Experimental mice were respectively pretreated with 200 and 400 mg/kg of MOHE, and 0.5% and 1% of butylated hydroxyanisole (BHA) for two weeks prior to the administration of 15 mg/kg of DMBA, respectively. Levels of xenobiotic metabolizing enzymes such as cytochrome (Cyt) P450 and Cyt b5, activities of reduced glutathione (GSH) and glutathione-S-transferase (GST) and renal aspartate amino transaminase (AST), alanine amino transaminase (ALT) and alkaline phosphatase (ALP), and content of protein and total cholesterol were measured to determine the nephrotoxicity caused by DMBA and to elucidate the ameliorating role of M. oleifera.


Single oral administration of 15 mg/kg of DMBA resulted in significant increases in Cyt P450 and Cyt b5 (P<0.01). The toxic effect of DMBA was justified by the significant decreases in the activities of GSH and GST in renal tissues (P<0.05). The levels of renal AST, ALT and ALP and protein content which are indicative of renocellular damage were also found decreased along with significant increase in total cholesterol content in DMBA-treated mice (P<0.01). The DMBA-induced alterations in the tissues were significantly reversed after pretreatment with 200 and 400 mg/kg of MOHE orally for 14 d (P<0.01).


The effects of MOHE in enhancing the levels of antioxidants and enhancing the levels of biochemical assays in DMBA-induced carcinogenesis are by reducing the formation of free radicals. This study rationalizes the ethnomedicinal use of M. oleifera for the protection against nephrotoxicity induced by chemical carcinogens.
