Abstract

The effect of ethanolic extract of Morinda citrifolia leaves and fruit on blood pressure in dexamethasone-induced hypertension rat was evaluated. Total phenolic content of Morinda citrifolia leaves ethanolic extract (MCLEE) and Morinda citrifolia leaves ethanolic extract (MCFEE) was 1.789 ± 0.116 and 1.677 ± 0.051 mg of gallic acid equivalents per gram sample, respectively. Rutin level in MCLEE was 0.92 ± 0.19%, and scopoletin level in MCFEE was 0.46 ± 0.05%. MCLEE, MCFEE, and its extract combination significantly decreased the blood pressure of hypertensive rats. The combination group showed highest hypotensive activity by lowering systolic blood pressure by 16.71 ± 3.95%, diastolic blood pressure by 21.49 ± 7.90%, and mean arterial blood pressure by 19.58% ± 6.35. All extract treatments have not been able to repair or inhibit renal damage caused by dexamethasone induction.

Keywords: Morinda citrifolia L; dexamethasone; hypotensive; renal rat; rutin; scopoletin.
