Smilax anceps is traditionally used in the management of rheumatism. Anti-nociceptive activity of the ethanol extract of the leaf of this plant was investigated. Phytochemical screening and acute toxicity (LD50) of the extract were determined. The acetic acid induced writhing and hotplate test were used to evaluate the anti-nociceptive activity in Swiss mice. Fifty animals divided into twenty-five each were used for each assay. Acetylsalicylic acid and tramadol were used as reference drugs while extract was administered at 250, 500 and 1000mg/kg doses via the oral route in writhing and hotplate test respectively. Flavonoids, tannins, saponins and steroids/triterpenoids were found as phytoconstituents. In acetic acid induced writhing test, a statistically significant (P |
