Background and Aim: Sarcocephalus latifolius is a medicinal plant commonly used in traditional medicine to treat various diseases. The aim of the present study is to evaluate the hepatoprotective activity of Sarcocephalus latifolius fruits aqueous extract against paracetamol-induced liver damage in rats. Material and Methods: Aqueous extract of Sarcocephalus latifolius fruits at doses of 100, 250 and 500 mg/kg were administered orally to rats with paracetamol-induced hepatotoxicity (1 g/kg). The treatment with the extract and paracetamol lasted 7 days. Silymarin (50 mg/kg) was given as reference control. All tested drugs were administered orally. Results: Our results show that the Sarcocephalus latifolius fruits extract induced a significant reduction (p < 0.05) of serum enzymes alanine aminotransferase (ALAT), aspartate aminotransferase (ASAT), alkaline phosphatase (PAL) and total bilirubin (TB). Then, the extract at the dose of 500 mg/kg showed a better protection (p < 0.001) of hepatocytes with a percentage of protection of 43.59% ± 2.03%;59.43% ± 4.12%;73.29% ± 5.72% and 62.55% ± 7.48% for ALAT, ASAT, PAL and TB, respectively. The histology of livers exposed to paracetamol shows an inflammation of the hepatocytes. In addition, there was a significant alteration of the liver parenchyma. The 500 mg/kg extract showed a resorption of the inflammation. Histopathological examination showed that the extract regenerated paracetamol-induced liver damage. Conclusion: Aqueous extract of Sarcocephalus latifolius fruits has hepatoprotective activity against paracetamol-induced hepatotoxicity in rats. But it would be important to evaluate the activity of aqueous extract of Sarcocephalus latifolius fruits on oxidative stress parameters in vivo in rats. .

The revaluation of medicinal plants in the veterinary pharmacopoeia is essential for the development of livestock in Burkina Faso. In order to justify the use of C. sesamoides and S. hermonthica in the treatment of gastrointestinal parasitosis of small ruminants, a quantification of phenolic compounds as well as antioxidant activity and acute toxicité evaluation of both plants were performed. Acute toxicity was evaluated by administering a single dose of 2000 mg/kg body weight of aqueous extract of both plants to mice. The highest total polyphenol content for C. sesamo?des was obtained in the ethyl acetate fraction with 47.236 ± 2.57 mgEAG/100mg while that of S. hermonthica was 74.871 ± 2.57 mgEAG/100mg obtained with the n-butanol Fraction. The dichloromethane extract of S. hermonthica obtained the highest total flavonoid content with 7.31 ± 0.48 mgEQ/100 while the highest total flavonoid content of C. sesamo?des was obtained with ethyl acetate fraction with 5.4273 ± 0.35 mgEQ/100mg. The aqueous extract of C. sesamo?des obtained the highest content of condensed tannins with 3.028 ± 0.13 mgEAT/100mg. Both plant’s extracts did not show any signs of toxicity in NMRI mice after administration of the dose of 2000 mg/kg. The antioxidant activity by DPPH, FRAP and ABTS methods was good compared to those of Quercetin and Trolox taken as standard.
