ABSTRACT (Download PDF )
The study investigated the hepatotoxic effect of the ethanolic extract of Chromolaena
odorata leaf on groups of male wistar albino rats. The rats were divided into 3 groups of 5
rats each .Group A and B which were the treated groups received 10mg/kg and 20mg/kg
body weight of the extract .Group C (control) was given 5% solution of tween 80 only. The
administration of the extract was done orally for a total period of 21 days .Blood samples
were collected at the end of the study and the results of the blood samples analysis showed
that group A, B, and C (control) had mean ALT levels of 10.4±3.32U/L,12.0±1.7U/L and
8.4±2.24U/L respectively while the mean AST levels were 20.2±4.66U/L, 23.8±4.65U/L and
24.0±5.59U/L respectively.There was no significant difference (P>0.05)in the levels of ALT
and AST among the 3 groups at 10mg/kg body weight dose level while there was significant
increase(p<0.05)in the ALT but no significant difference in the AST levels at 20mg/kg body
weight dose level between the treated and non-treated groups . The results of the study
showed that the ethanolic extract of Chromolaena odorata leaf at 10mg/kg body weight dose
level had no adverse effect on the liver of the experimental rats while at 20mg/kg body
weight it might be toxic to the liver. So the dose for human should be limited to less than
20mg/kg body weight dose level
Keywords: Chromolaena odorata, hepatotoxicity ,blood samples, ethanolic extract.
