Antihypertensive activity of ethanol extract combination of Anredera cordifolia (Ten.) v. Steenis and Sonchus arvensis L. leaves on angiotensin II- induced male wistar rat

Abstract

Hypertension is an important risk factor of cardiovascular disease which is the leading cause of death. Traditionally, many plants are used to lower blood pressure including Anredera cordifolia (Ten.) v. Steenis and Sonchus arvensis L.. Previous studies found that both plants showed antihypertensive activity through inhibiting angiotensin converting enzyme and inducing diuresis. The aim of this study is to evaluate the antihypertensive effect of Anredera cordifolia (Ten.) v. Steenis leaves extract (ACLE) and Sonchus arvensis L. leaves extract (SALE) combination on hypertensive animal induced with angiotensin II. In this study, blood pressure measurement was done using CODA® tail-cuff blood pressure system plethysmograph. After initial measurement of blood pressure, extracts were administered orally according to the respective groups as follow: ACLE 50, ACLE 100, SALE 50, SALE 100, ACLE-SALE 25-25, and ACLE–SALE 50-50 mg/kg bw. After 1 hour, angiotensin II 100 µg/kg bw was administered then the blood pressure was re-measured. ACLE 50 and ACLE-SALE 25-25 mg/kg bw were able to significantly lower blood pressure compared to positive control group (p
