The stem bark and leaves of Daniellia oliveri were screened phytochemically and the effects of their respective methanol extracts on the skeletal muscle of rats were investigated using the isolated phrenic nerve hemidiaphragm muscle preparation. Both were found to contain tannins, cardiac and saponi

β¦ Synopsis
The effects of oral and intravenous administration of the stem bark extract of vitex doniana on blood pressure was investigated in normotensive and hypertensive rats. Oral and intravenous administration of the stem bark extract produced a dose-dependent hypotensive effect in both normotensive and hypertensive rats. The blood pressure was markedly reduced and the reduced level maintained for longer duration when the extract was administered intravenously to hypertensive rats. The present data show that the extract affects the smooth muscle of the vascular system, suggesting a possible therapeutic application as an antihypertensive agent.
