Abstract
- Three different extracts of Matricaria chamomilla L. were evaluated for their antihypertensive activity, these extracts were total alcohol extract (Extract 1), oil extracted (Extract 2), and water lifted after oil extraction (Extract 3). Quantitative and Qualitative analyses were carried out for all extracts. The 3 extracts were proved to be safe for human use. A single oral administration of the plant extracts (200 mg/kg) decreases both systolic and diastolic blood pressure of normotensive rats after 1, 1.5, and 2 hr. Furthermore, groups treated with the evaluated extracts (100 & 200 mg/kg) or Captopril (20 mg/kg) showed a significant reduction in the elevated blood pressure and heart rate. Extract 3 showed the most antihypertensive activity. Serum biochemical parameters and lipid profile levels of treated groups were improved in comparison with induced-hypertensive untreated rats. In evaluation of oxidative damage parameters Glutathione and superoxide dismutase (SOD) in some organs, the investigated extracts or captopril restored the amount of reduced Glutathione in tissues in addition to an increase in the activity of the SOD after a significant depletion of SOD activity. In the clinical study, there was a significant dose dependent decrease in Systolic blood pressure, Diastolic blood pressure, and heart rate compared with their basal values in both normotensive and hypertensive human volunteers after oral administration of Matricaria chamomilla beverages.
