Nutrient Composition and Selected Biochemical Effects of Cnidoscolus aconitifolius Leaf Extracts in Male Albino Rats

Abstract
The present study evaluated nutritional constituents of Cnidoscolus aconitifolius leaf and examined the effect of aqueous and ethanol extracts on selected biochemical parameters using male albino rats. Forty five male albino rats weighing (115-121 g) were used for the study. The rats were randomly divided into nine groups of five rats each. Group I served as the control while the other groups were administered 200, 400, 600 and 800 mg/kg body weight of aqueous and ethanol leaf extracts. Mineral, proximate and vitamin analysis showed that the plant leaf contains appreciable amount of vitamin and minerals analysed. Results showed significant difference (P<0.05) between the control and Cnidoscolus aconitifolius leaf extracts administered rats with respect to body weight changes, liver function indices and haematological parameters (White Blood Cells) in dose dependent ratio. From this study, aqueous leaf extract of Cnidoscolus aconitifolius at doses of 400, 600 and 800 mg/kg body weight showed evidence of cumulative toxicity. It is therefore suggestive to say that in order to ensure holistic safe utilization, bioactive constituents of Cnidoscolus aconitifolius leaf may be better extracted using ethanol as it has not shown any evidence of hepatotoxicity.
