Objective:To investigate the analgesic and anti-inflammatory effects of the methanolic extract of the leaves of Triumfetta rhomboidea on mice and rats respectively.And to screen the phytochemical constituent of the extract. Methods:The analgesic effect was determined by acetic acid-induced writhing test in mice.While the anti-inflammatory activity was determined by egg albumin-induced oedema of the rat paw.Phytochemical screening was done by standard procedures.Results:Triumfetta rhomboidea leaf extract(50 -400 mg/kg) caused a statistically significant inhibition on the egg albumin-induced eodema or inflammation in Wister albino rats with P<0.001(ANOVA).This effect was higher than the observed effect with Piroxicam(0.5 mg/kg) which was used as a standard.The effect was also dose-dependent.Furthermore,Triumfetta rhomboidea extract caused a statistically significant reduction in the number of acetic acid-induced writhing in mice,with P<0.001(ANOVA).These effects were also does-dependent and greater than the analgesic effects by paracetamol which was used as a reference drug.Phytochemical screening revealed the presence of flavonoids,steroids, triterpenoids alkaloids,tannins and saponins in Truimfetta rhomboidea leaf extract.Conclusion:Triumfetta rhomboidea can be recommended for acute inflammatory disorders and diseases associated with pains.This also supports its traditional use as an anti-snake bite and anti-cancer or anti-tumor agent.Further study is on the way to find out the mechanism of its action and also to isolate,identify and characterize the active principle responsible for these effects in this plant.
