The leaf of Picralima nitida has been used ethanomedicinally used in the treatment of ulcers, diabetes, sexual impotence and hypertension. To evaluate the pharmacognostic properties and anti-ulcer activity of the ethanol crude extract and fractions of Picralima nitida leaves. The Pharmacognistic properties of the dry leaves were determined using standard method. The leaves were extracted using ethanol, the acute toxicity was determined. The crude ethanol extract was then fractionated using solvents of increasing polarity (n-Hexane, ethyl acetate, butanol and water) fraction. The qualitative and quantitative phytochemical constituents and the antiulcer evaluation were performed on ethanol induced in wister rats using standard method. Picralima nitida leaf shows the presence of saponins, terpenoids, Alkaloids, glycosides, flavonoids. The crude ethanol extract has high safety margin. A significant reduction in antiulcer activity was found in 500mg ethanol crude extract and butanol fraction when compared to the standard drug (Famotidine). The
