Objective: To investigate the antioxidant and hepatoprotective effects of ethanolic Mangifera indica (M. indica) seed extract on carbon tetrachloride (CCl4)-induced hepatotoxicity in albino rats.
Methods: Forty-eight albino rats weighing (100-150 g) were used for hepatoprotective and toxicity experiments. Antioxidant activity was determined using the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay. The toxicity of M. indica seeds on the liver was evaluated by examining wellness parameters, body weight, and liver histological sections. The protective effects of 50 mg/kg and 100 mg/kg of seed extract on CCl4-induced hepatotoxicity were investigated by evaluating hematological, renal, and liver function parameters, body weight, and liver histological sections.
Results: The antioxidant activity of the M. indica ethanolic extract was (92 ± 0.03 RSA %) compared with (91 ± 0.01 RSA %) of propyl gallate, and the IC50 was (8.3 ± 0.01 µg/ml) and (14.1 ± 0.01 µg/ml). No changes were observed in the health indicators, body weights, and liver histological sections following oral administration of 50 mg/kg and 100 mg/kg of M. indica seed extracts. Treatment with M. indica seed extract significantly reduced alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), blood sugar, and urea levels compared with those in the CCl4-treated group.
Conclusion: The IC50 of the M. indica ethanolic extract was 8.3 µg/ml, and the M. indica extract is a potential source of natural antioxidants that protect against CCl4-induced hepatotoxicity.
