Hypertension is a main cause of approximately 66% of cardiovascular disease in 15 countries in the Asia Pacific region, including Indonesia. The high cost of treatment and the side effects of drugs are causes of the lack of public awareness in dealing with hypertension. In Indonesia,
Andrographis paniculata [Burm.f.] Ness grows abundantly, and is widely used as a traditional medicine such as in treatment of hypertension. This study aimed to evaluate the antihypertensive activity of the ethanolic extract of
A. paniculata herbs (EEAP) in Wistar rats with a non-invasive method. In the study, the herb was extracted by 90% ethanol, and identified for its andrographolide, flavonoids and phenolics contents. Antihypertensive activity was evaluated using CODA “Non Invasive Blood Pressure (NIBP) system with Volume Pressure Recording method”. High blood pressure was induced with an alpha adrenergic receptor agonist, phenylephrine (0.9 mg/kgBW). EEAP at doses of 45, 90 and 180 mg/kgBW was evaluated for its antihypertension in comparison to nifedipine (10.8 mg/kgBW). Blood pressure measurements were performed 3 times i.e. before induced (baseline), 15 and 45 minutes after phenylephrine administration. Based on TLC-densitometric data, andrographolide, total flavonoids and total phenolics contents in EEAP were 12.85 ± 0.46%, 0.72 ± 0.01% and 1.66 ± 0.01%, respectively. EEAP exhibited a potent antihypertensive activity in phenylephrine-induced hypertensive rats. EEAP could decrease systolic and diastolic blood pressures up to 120% and 150%, respectively. EEAP fractions are potential to develop as a hypotensive agent in hypertension therapy.
