Standardized ethanol-water extract of Ficus deltoidea Angustifolia reduces blood pressure in spontaneously hypertensive rats
2019
ABSTRACTFicus deltoidea is used in Malay traditional medicine for the treatment of a number of disorders, including hypertension. There is, however, no scientific evidence on its anti-hypertensive effects. This study, therefore, investigated the effects of a standardized ethanolic-water extract of Ficus deltoidea Angustifolia (FD-A) on blood pressure (BP) in spontaneously hypertensive rats (SHR). Male SHR with systolic BP of >150 were divided into 4 groups (n = 8) and given either FD-A (800 or 1000 mg kg−1 day−1) or losartan (10 mg kg−1 day−1) or 0.5 ml of distilled water (control) daily for 28 days. BP, body weight, food and water intake, serum and urinary electrolytes, endothelin-1 (ET-1), total antioxidant capacity (TAC) and components of the renin-angiotensin-aldosterone system were measured. Data were analyzed using ANOVA with statistical significance set at p < 0.05. Following treatment, BP, heart rate, and heart weight in FD-A and losartan-treated rats were significantly lower than those in the con...
