Scavenging Effects of Aspalathus Linealis (Rooibos Tea) on Active Oxygen Species
Rooibos tea ia a totally unique South African product of the plantAspalathus linealis which is only produced in the Cadarberg mountains around Clanwilliam. In South Africa it is mainly used as a substitute for the Oriental black tea by people who enjoy it either hot or cold, or by those who regard it as a healthy drink. Clinically, Rooibos tea is often prescribed for nervous tension, allergies, stomach and digestive problems. For evaluation of its antioxidant action, reactivity of Aspalathus linealis, ascorbic acid, and quercetin which is one of non-glycosidically linked flavonoids included in Asparathus linealis, to various reactive oxygen species were assessed by electron spin resonance (ESR) sipectrometry using 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) as a spin trapper1,2.
