Some cardiovascular effects of the aqueous extract of the leaves of Stachytarpheta jamaicensis L. Vahl.
The effect of the aqueous extract of the leaves of Stachytarpheta jamaicensis (collected from
Nigeria in February 2004) on blood pressure was investigated in anaesthetized
normotensive male rabbits. The extract was administered intravenously at doses ranging
from 2.5 to 80 mg kg-1. The extract caused a dose-dependent fall in blood pressure and
heart rate. A concentration of 2.5 mg kg-1 of the extract reduced the Mean Arterial Pressure
(MAP) from the initial 102.8±4.2 to 96.6±7.3 mm Hg and the Heart Rate (HR) from 398.3±8.3 …
