To investigate the antipyretic activity of hydro-methanol extract of Melia azedarach Linn. (HMEMA) seeds and Cucumis melo Linn. (HMECM) seeds in experimental animals. Baker’s yeast was used to induce fever in rabbits which were divided into six groups. The animal groups were thereafter administered distilled water (control), paracetamol (reference standard, 150mg/kg), HMEMA (250mg/kg), HMEMA (500mg/kg), HMECM (250mg/kg) and HMECM (500mg/kg) respectively. HMEMA and HMECM were also phytochemically screened for tannins, alkaloids, phenols, flavonoids, saponins and cardiac glycosides. Results indicate that hydro-methanol extract of M. azedarach Linn. Seeds (250mg/kg and 500mg/kg) significantly (p<0.001, p<0.05 respectively) reduced the elevated body temperature in dose dependant manner. Insignificant to no antipyretic effect was produced by hydro-methanol extract of Cucumis melo L. seeds. Phytochemical analysis of the HMEMA showed the presence of flavonoids, saponins, tannins, phenols, alkaloids and cardiac glycosides While HMECM was positive for flavonoids, phenols and saponins. The result shows that there exists a potential benefit in utilizing Melia azedarach L. seeds in treating fever. This property can be attributed to the presence of phytochemical constituents present in the hydro-methanol extract of Melia azedarach L. seeds and the exact mechanism need to be evaluated. Keywords: Medicinal plants, antipyretic activity, Baker’s yeast, hydro-methanol extract, phytochemical screening.
