Toxic effects of the extracts of Eugenia uniflora Linn. in rats

Abstract

The toxi effects of the leaves of Eugenia uniflora Linn on rats was evaluated by observing abnormal changes in the haemogram including erythron and leukogram, serum biochemical parameters, histopathology, and hexobarbital sleeping time. The leaf extract produced significant increases in the packed cell volume (PCV)  haemoglobin concentration and total red blood cell counts (P.05) but did not influence the blood coagulation  time. Similarly the leaf extract of Eugenia uniflora produced significant increases (P.05) in the serum  activities of alanine aminotransferase and aspartate a rninotrasfemse. Although the extract did not produce histological lesions of the liver, the increases in liver enzyme activities could be due to incipient liver damage.
