Sum of all (n = 7) phenolic acids (µmol/L) in fermented faecal fluids from older (n = 4) and younger (n = 6) adults (over 24 h of fermentation). The white boxes represent t = 0 h, the light shaded boxes   t= 6 h and the dark shaded boxes, t = 24 h. Boxes representing the older group are labelled “O”, boxes representing the younger group are labelled “Y”. #There was a statistically significant increase in the sum of PA in younger adults over time in the blank fermentations (p < 0.001) and when rutin and raftiline were combined (p = 0.001). § There was a statistically significant increase in the sum of PA in older adults over time in the fermentations with rutin alone (p = 0.04)
