The hematopoietic potential of methanolic and aqueous extracts of Portulaca oleracea in a phenylhydrazine model of anemia

OBJECTIVE: Portulaca oleracea, commonly known as Purslane, is traditionally used as a sour, diuretic, and cooling herb with hemostatic properties. The present study evaluates the antianemic effect of methanolic and aqueous extracts of P. oleracea in a phenylhydrazine model of anemia. MATERIALS AND METHODS: Phenylhydrazine (60 mg/kg/day, i.p., two consecutive days) was used to induce anemia in rats. The aqueous and methanolic extracts of P. oleracea were prepared, and three methods of treatment were defined with two doses (500 and 750 mg/kg, i.p.). The hematological parameters and blood cell morphology, total and direct bilirubin, and morphology, and pathology of bone marrow were evaluated. RESULTS: The results showed that the methanolic extract has better effects than aqueous extract in improving phenylhydrazine-induced anemia. Our results showed that administration of 500 and 750 mg/kg of P. oleracea methanolic extracts for 4 days could protect against the development of anemia caused by phenylhydrazine. CONCLUSION: In summary, the methanolic extracts of P. oleracea might be effective in phenylhydrazine-induced anemia.
