Figure 2.

Proposed microbial degradation of aspalathin, nothofagin and their flavones, following non-microbial oxidative conversion at high pH conditions, found in the small intestine [69] (shaded area). The figure was adapted from Muller et al. [8]. Glc = glucose; R = OH for aspalathin and metabolites; R = H for nothofagin and metabolites.
