Type: Research



In the yuletide, plant extracts, animal fluids, roots, stems and leaves have been consulted by man in his vide to overcome hunger, illness and ignorance. Alligator is one of those plants whose seeds are of research interest in this study. Its effect on some of the biochemical and hematological indices of albino Wister rats were investigated.

Twenty four (24) Albino Wistar rats weighing 120 - 150g were divided into two (2) groups. Group A (12 rats) served as control while group B (12 rats) served as the test rats. The extraction of the aqueous extract was done by cold maceration of pulverized seeds in absolute sterile water for 24 hours. The extract was filtered and concentrated in rotary evaporators at 40oC.

The central group was given normal rat feed and water. While the test rats received 1 ml of the extract. Both groups were given rat feed and water ad libitium for 28 days. At the end of the feeding, blood samples were collected from the animals by cardiac puncture and 2.0ml each were placed in anticoagulant bottles containing E DTA (Ethylene diamine tetracetic acial for hematological tests while 3.0 ml were placed in plain bottles and left to clot and the serum extracted for biochemical analysis. Results from the analysis showed a significance increase in white blood cell counts (PLO. 05) and reduced hemoglobin levels and packed cell volume (PLO .25) in the test rats, there is no effect in platelet counts, creatinin, urea and the electrolyte. It could be deduced that aqueous extract of Aframomum melegueta (Alligator pepper) has adverse effect on haemopoiesis and no effect on the kidney using the safe dose.
