    <subfield code="a">&lt;p&gt;The study aimed to determine the toxicity level of aqueous leaf extract of &lt;em&gt;Diospyros mespiliformis&lt;/em&gt; on&amp;nbsp; Wister albino rats and the phytochemical and proximate composition of &lt;em&gt;Diospyros mespiliformis&lt;/em&gt;. The plant extract was found to contain Tannin, Saponin, flavonoid, glycoside, volatile fatty acid and Resin as constituent following phytochemical analysis.&amp;nbsp; On further study using proximate analysis shown that the following constituents&amp;nbsp;were found moisture (1%), Ash (7%), lipid (1.5%), fibre (2.5%), Nitrogen (1.89%), crude protein (11.81% and Carbohydrate (74.3%).&amp;nbsp; Sub-chronic toxicity studies of aqueous leaf extract of &lt;em&gt;Diospyros mespiliformis&lt;/em&gt; was conducted following 28 days administration of 1000, 2000 and 3000mg/kg to three group rats respectively, while the fourth group served as a control. Change in body weight, haematological and serum biochemical parameters as well as gross post changes used as indices of toxicity. The percentage yield of the extract was 16.0%. These were inappetence and weight loss in the first week of the study in the experimental groups but were no significant changes in body weight, haematology and serum biochemistry (P&amp;gt;0.05). It can&amp;nbsp;therefore&amp;nbsp;be inferred that this extract is safe at a dose of 3000mg/kg in rats following consecutive daily administration for 28 days.&lt;/p&gt;</subfield>
