Ethanolic Extract of Mangifera indica Protects against CCl4-Induced Hepatotoxicity via Antioxidant Capabilities in Albino Rats.

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.
