ANTI-ULCER ACTIVITY OF STEM BARK OF DANIELLIA OLIVERI

Abstract

The MeOH extract of Daniellia oliveri showed a dose related activity on the induced ulcers. The 500mg/kg extract had an activity (P<0.05) compared with vehicle. The reference drug, cimedtidine, used in the test at 100mg/kg did not show any activity in the ASA-induced ulcers. The effect of the extract on acetylcholine (Ach) induced contraction on rat duodenum was also assessed. Like the reference antagonist, atropine, used in the test, the extract showed a non-competitive antagonism on the induced contraction. This anti-spasmodic effect of the extract could partly explain the anti-ulcer effect. This is the first report on the anti-ulcer activities of the methanolic extract of D. oliveri stem bark.
