ABSTRACT The brewed tea extracts of the green and yellow breadfruit leaves were evaluated for their antihypertensive potential using Sprague-Dawley rats. There was significant attenuation (20-30 mm Hg) of the angiotensin II-mediated hypertension in the animals treated with the tea extracts. The antiinflammatory and antioxidant activities of these extracts were determined. The antioxidant activities of the brewed whole green leaf and yellow leaf teas, measured by fluorescence spectroscopy using a model liposome system, were 90.2% and 80.5%, respectively. The yellow and green leaf whole teas displayed moderate cyclooxygenase (COX)-1 and -2 enzyme inhibitory activities.
