Ethanol leaf extracts of Anogeissus leiocarpus in antioxidants and hepatotoxic effects of Escherichia coli O157:H7 infected Swiss Mice.

Introduction: Diseases caused by bacteria can be managed with medicinal plants with rightful dosage that will not affect body physiology and organs.

Aim: This research aimed to evaluate the antioxidants and the effects of Anogeisus leiocarpus on liver function.

Materials and methods: Ethanol leaf extracts were processed for antioxidants and hepatotoxic effects using animal models. Group one (negative control) was given access to water and regular feed, group two (positive control) was dosed with 107 CFU/ml of Escherichia coli O157:H7, and groups 3-6 were dosed with 107 E. coli O157:H7 for 3 days and treated with extract concentrations of 12, 25, 50 and 100 mg/kg bw respectively for seven days.

Results: Higher ascorbic acid values in Ferric reducing antioxidant property (FRAP) and Hydroxyl radical scavenging (HRS) were recorded in the positive control (0.05 ± 0.01, 41 ± 0.05) than in the extract-treated (0.02 ± 0.14, 30 ± 0.02). Increase in DPPH (47 ± 0.1268 ± 0.05 %), Free radical scavenging property (FRAP) (0.03 ± 0.02-0.08 ± 0.14 %), and HRS (38 ± 0.14-68 ± 0.12 %) was observed in the extract. The lipid peroxidation (LPO) of the quote was 78.51 ± 2.16, GSH was 36.18 ± 3.18, and catalase was 78.42 ± 4.713. In the extract-treated, decreased values were recorded for LPO ((108.36 ± 1.12-70.19 ± 1.68 μM/g), while increased values were observed in Glutathione (GSH) (25.11 ± 2.64-33.62 ± 1.35 μM/g), and catalase (54.18 ± 2.14-60.25 ± 1.4 μM/g). The values of negative control for Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), and Alkaline phosphate (ALP) were lesser than what was received in the extract treated.

Conclusion: The plant's traditional medicine usage is effective at low dosage and could be a suitable candidate for drug development which will not affect the body's physiology and organs. The subjecting of A. leiocarpus ethanol leaf extract to antioxidants assays and its effect on liver function have further proved its value in folklore medicine.
