Abstract

The considerably high incidence of cardiovascular disease in Indonesia has attracted scientists to investigate various plant and fruit extracts as preventive agents. Averrhoa bilimbi (AB) is rich in bioactive constituents that may be ef�fective in preventing indicators of hypertension. This study evaluated the roles of AB extract in increasing serum nitric ox�ide (NO) concentration and vascular dilatation in ethanol-induced hypertensive rats. A total of 24 male Wistar rats (Rattus norvegicus) were divided equally into 4 treatment groups (n=6): P0 (control group, administered placebo); P1 [adminis�tered captopril 3 mg/kg body weight (BW) orally]; P2 (administered AB extract at 20 g/kg BW); and P3 (administered AB extract at 40 g/kg BW). The AB extract was obtained from fresh AB macerated in 96% ethanol and was subjected to bioactive compounds identification using thin layer chromatography. After pretreatment with ethanol for 15 days, treat�ments were administered daily for 14 days. All rats were measured for tail blood pressure by the tail-cuff method and NO concentrations by avidin-horseradish peroxidase sandwich-enzyme-linked immunosorbent assays. All rats were sacrificed to collect blood vessels for histopathology. The results showed that AB extracts contained flavonoids, saponins, polyphe�nols, essential oils, and anthraquinone. Treatment with AB extract at a dose of 40 mg/kg BW significantly increased NO concentrations (P<0.05). Histopathological analysis showed that AB extracts inhibited endothelial pyknosis, intimal body, and adventitial leukocyte infiltration of posterior vena cava blood vessels. These results suggest that the protective effect of AB extracts is associated with NO concentration in the blood by inhibiting blood vessel dysfunction
