BACKGROUND
The genus Amaranthus has potential activity as a hepatoprotective agent.
OBJECTIVE
The present pharmacological investigation focuses on evaluation of the efficacy of aqueous extract of roots of Amaranthus tricolor Linn. for their protection against paracetamol (PCM) overdose induced hepatotoxicity.
METHODS
The aqueous extract of roots of A. tricolor Linn. was prepared and phytochemical screening was done. The biochemical investigation viz. serum glutamic oxaloacetate transaminase (SGOT), serum glutamic pyruvate transaminase (SGPT), alkaline phosphatase (ALP) and total Bilirubin (TB) was done against PCM-induced hepatotoxicity in wistar albino rats. The histopathological studies of liver were also done.
RESULTS
The phytochemical screening of the aqueous extract showed the presence of alkaloids, carbohydrates, flavanoids, amino acids, proteins, fixed oil, saponins and tannins, and phenolic compounds. Pretreatment with the aqueous extract of root significantly prevented the physical, biochemical, histological, and functional changes induced by paracetamol in the liver. The extract showed significant hepatoprotective effects as evidenced by decreased serum enzyme activities like SGPT, SGOT, ALP, and TB, which was supported by histopathological studies of liver. The aqueous extract showed significant hepatoprotective activity comparable with standard drug silymarin as well as hepatotoxin drug PCM.
CONCLUSIONS
From these results, it is concluded that the A. tricolor has potential effectiveness in treating liver damage in a dose dependent manner.
