---|---|---|---|---|---|---|---|---|
Lippia adoensis | Verbenaceae | Leaves | Aqueous (200 and 400 mg/kg | CCl4-induced | Hepatocyte regeneration and peripheral mononuclear infiltration are reduced in comparison to CCl4 | Albumin and total protein levels increased, while AST, ALT, ALP, and TBIL levels reduced | — | [107] |
Ethanol (200 and 400 mg/kg) | CCl4-induced | Hepatocyte regeneration was observed when compared to CCl4 | Total protein and albumin increased while AST, ALT, ALP, and TBIL reduced | — | [107] | |||
Ensete ventricosum | Musaceae | Cheesman | Methanol (200 and 400 mg/kg) | Isoniazid and rifampicin- induced | Hepatocyte regeneration was observed when compared to isoniazid and rifampicin-induced hepatocyte induced | A dose of 400 mg/kg and 100 mg/kg of silymarin significantly decreased ALT, AST, ALP, and TBIL when compared to isoniazid and rifampicin | — | [108] |
Thymus serrulatus | Lamiaceae | Aerial parts | Essential oil (200 μL/kg) | Paracetamol—induced | Except for a few inflammatory cell infiltrations, normal hepatocytes were seen in 200 μL/kg EO | When compared to paracetamol, AST, ALT, and ALP levels were reduced | — | [109] |
Thymus schimperi | Lamiaceae | Aerial parts | Essential oil (200 μL/kg) | Paracetamol—induced | Except for certain inflammatory cell infiltrations, 200 μL/kg EO revealed normal hepatocytes | When compared to paracetamol, AST, ALT, and ALP levels were reduced | — | [109] |
Justicia schimperiana | Acanthaceae | Leaves | Methanol (200 mg/kg) | CCl4-induced | The mice's livers were significantly protected from CCl4-induced damage | AST and ALT were significantly suppressed compared to CCl4 | 1000 | [110] |
Verbascum sinaiticum | Scrophulariaceae | Leaves | Methanol (200 mg/kg) | CCl4-induced | The mice's livers were significantly protected from CCl4-induced damage | In comparison to CCl4- induced rats, AST and ALT were significantly reduced | — | [110] |
Phytolacca dodecandra | Phytolaccaceae | Root | Methanol (200 and 400 mg/kg) | CCl4-induced | 200 and 400 mg/kg doses, normalized the defects in the histology of the liver of mice treated with CCl4 nearly to the level of the negative control group | ALP, ALT, AST, GGT, LDH, and bilirubin levels were all significantly lower, whereas albumin and total protein levels were significantly higher. At 400 mg/kg, the extract had a hepatoprotective effect comparable to silymarin | 2000 | [111] |
Satureja punctata | Lamiaceae | Aerial part | Aqueous (250 and 500 mg/kg) | Nitrillotriacetate-induced | Showed a normal lobular pattern with minor necrosis and lymphocyte infiltration that was comparable to the control and silymarin-treated groups | When compared to Fe-NTA administered controls, ALP, ALT, and AST levels were considerably lower | 2000 | [112] |
Solanecio angulatus | Asteraceae | Leaves | Methanol (200 and 400 mg/kg) | Nitrillotriacetate-induced | Not reported | ALP, ALT, and AST levels were significantly lower than Fe-NTA administered controls | 2000 | [112] |
Cucumis ficifolius | Cucurbitaceae | Root | Methanol (125, 250, and 500 mg/kg) | CCl4-induced | Improved the histology of the liver in mice treated with CCl4 to nearly the same level as the positive control group silymarin in 500 mg/kg doses | ALP, ALT, and AST levels were lower in these animals than in CCl4-induced mice. The 500 mg/kg dose showed the greatest hepatoprotective effect | 2000 | [94] |
Clutia abyssinica | Euphorbiaceae | Leaves | Methanol (200 and 400 mg/kg) | CCl4-induced | Inflammatory cells, vascular congestion, cellular degradation, necrosis, and vacuoles were reduced or absent | AST, ALT, and ALP levels were significantly lower than CCl4-induced controls. The higher dose (400 mg/kg) had a better hepatoprotective effect | 2000 | [113] |
Rumex abyssinicus | Polygonaceae | Rhizome | Methanol (125, 250, and 500 mg/kg) | CCl4-induced | At 500 mg/kg, the architecture was maintained, there was modest necrosis, and there were minor lymphocytic infiltrates | AST, ALT, and ALP levels were markedly decreased and were comparable to silymarin (100 mg/kg) at 500 mg/kg | 2000 | [114] |
Croton macrostachyus | Euphorbiaceae | Root bark | Ethanol (200 and 400 mg/kg) | Paracetamol-induced | Hepatocytes were normal and liver cells were regenerated at 400 mg/kg | In comparison to paracetamol induced the level of AST, ALT, ALP, and total bilirubin was lowered at a higher dose (400 mg/kg) | 2000 | [115] |
Cineraria abyssinica | Asteraceae | Leaves | Methanol (200 mg/kg) | CCl4-induced | Minor necrosis and focal inflammation | AST, ALT, and ALP levels were markedly decreased and were comparable to silymarin (100 mg/kg) at 500 mg/kg | 3000 | [116] |
Cordia africana | Boraginaceae | Stem bark | Methanol (100, 200, and 400 mg/kg) | Acetaminophen-induced | It showed moderate necrosis and vacuolar degeneration at 400 mg/kg | The level of AST, ALT, and ALP was decreased at a higher dose (400 mg/kg) compared to acetaminophen-induced | 3000 | [117] |
Terminalia brownii | Combretaceae | Leaves | Methanol (250 and 500 mg/kg) | CCl4-induced | At 250 mg/kg, the hepatocyte cell membrane's structural integrity was only marginally protected; however, at 500 mg/kg, there was no ballooning and a significant level of protection | The levels of ALP, ALT, and AST were lower than those in mice that had been CCl4-induced. Especially in terms of preserving ALT and AST levels, the percentage of hepatoprotective activity at 500 mg/kg was comparable to the standard drug silymarin at 100 mg/kg | 5000 | [118] |
