METHODS The rare enolic phenylpyruvic acid-2-O-glucoside, (PPAG:Z-2-(β-D-glucopyranosyloxy)-3-phenylpropenoic acid), is one of the major constituents of fermented rooibos infusions. 3-Phenylpyruvic acid (2-oxo-3-phenylpropanoic acid), without the sugar moiety and with a keto form instead of an

Rooibos (Aspalathus linearis) contains a rich complement of polyphenols, including flavonoids, considered to be largely responsible for its health promoting effects, including combatting obesity. The purpose of this study was to examine the effect of fermented rooibos hot water soluble solids on in
