Effect Of Aqueous Leaves Extract Ofcarica Papaya (Pawpaw) On Liver Enzymes In Normal Albino Rats.

ABSTRACT

The effect of aqueous leaves extract of Carica papaya (Linn) on some liver enzymesi.e; alanine aminotransferase ALT, aspartate aminotransferase AST, and alkaline phosphatase ALP, wasinvestigated.The phytochemical screening of the leaves extract of C.papaya was carried out at the beginning of the study.  Albino rats weighing between 73-93g, of both sexes were used for the study.Caricapapaya2 ml of 0.11 g/ml aqueous leaves extract was orally administered daily to each of the experimental rats for 7 and 14 days period of the study respectively,using stomach canula and the parameters were of liver function analysed using standard methods.The phytochemical screening revealed the presence of alkaloids,glycosides,saponins,phenols,flavonoids,proteins.The result also  indicated that, the leaves extract of Carica papaya (pawpaw) causes a significant increase(p0.05) in all the parameters of liver function under the study. Therefore, it was was concluded that the aqueous leaves extract of Carica papaya might caused acute toxicity to the liver if consumed in large quantity and it also appeared to have no chronic toxicity.
