Rooibos flavonoids

Bramati, L. et al.. Quantitative characterization of flavonoid compounds in Rooibos tea (Aspa-lathus linearis) by LC-UV/DAD, J. Agric. Food Chem., 50, 5513, 2002. 

The dihydrochalcones aspalathin and nothofagin have been identified as the main flavonoids in the South-African Rooibos tea (Aspalathus linearis) [41]. 

The use of natural antioxidants in supplements can also exhibit pro-oxidant activity under certain conditions such as the concentration and nature of the polyphenolic compounds causing oxidative damage to important cellular components (48). Aqueous extracts and erode polyphenolic fractions of both traditional and green rooibos were evaluated for possible pro-oxidant activity using a Fenton reaction model system containing FeCb-EDTA and H2O2 for the generation of hydroxyl radicals. Pro-oxidant activity was shown for pure aspalathin while the dihydrochalcone and flavonoid contents of the enriched...
