Ethyl Acetate and Aqueous Fractions of Ziziphus jujuba Prevent Acute Hypertension Induced by Angiotensin II in Rats

Background: The effect of hydroalcoholic extract of Ziziphus jujuba (ZJ) on hypertension has been reported previously. Objective: This experiment investigates the effect of two ethyl acetate (EA, a polar and semi-polar compound) and aqueous fractions (AQ, a polar compound) of ZJ extract on cardiovascular parameters in acute hypertension induced by angiotensin II (AngII). Methods: Rats were randomly divided into following groups (n=7 in each...
