Abstract
OBJECTIVES
The study aimed to determine the phytochemical profile and safety of the aqueous extract of Pleurotus tuber regium using laboratory animal model.
METHODS
The pulverized sample was macerated with water and allowed to stand for 24 h, then filtered. Preliminary qualitative phytochemical screening was carried out on the crude extract and LD50 determination was done using standard procedures. Haematological and serum biochemical parameters to assess the kidney and liver functions were carried out using standard methods.
RESULTS
The phytochemical screening revealed the presence of alkaloids, cardiac glycosides, saponins, phenolic compounds, tannins, steroids, carbohydrates, flavonoids and terpenoids. However, anthraquinones were observed to be absent in the extracts. The LD50 of the extract was found to be greater than 5,000 mg/kg when administered orally with no physical signs of toxicity and death over the 14-day period. There was no significant (p>0.05) increase in the level of serum alanine aminotransferase, aspartate transaminase, alkaline phosphatase, blood urea nitrogen and creatinine (p<0.05) when compared to the control group. There was a significant (p<0.05) increase in the total white blood cells of the mice administered with P. tuber-regium.
CONCLUSIONS
This study showed that P. tuber-regium (Fr.) Singer does not possess toxic principles, hence, the wide safety margin observed in the mice.
