The captions of Figures 1 and 2 have been updated (to include peak numbers) as follows: Figure 1. MRM trace chromatograms of (epi)catechin-Oglucuronides (465/289) (peaks 1, 2, and 3), (epi)catechin sulfates (369/289) (peaks 4 and 5), O-methyl (epi)catechin-O-glucuronides (479/303) (peaks 6 and 7), and O-methyl (epi)catechin sulfates (383/303) (peaks 8, 9. and 10) detected in urine samples after intake of almond extract. The MRM trace chromatogram corresponding to (epi)catechin (289/245) is also shown to confirm metabolites. Figure 2. MRM trace chromatograms of 5-(dihydroxyphenyl)γ-valerolactone glucuronide derivatives (383/207) (peaks 11 and 12), 5-(dihydroxyphenyl)-γ-valerolactone sulfate derivative (287/207) (peaks 13), 5-(hydroxymethoxyphenyl)-γ-valerolactone glucuronide derivatives (397/221) (peaks 14 and 15), and 5-(hydroxymethoxyphenyl)-γ-valerolactone sulfate derivatives (301/221) (peaks 16 and 17). MRM trace chromatograms of aglycones, 5-(dihydroxyphenyl)-γ-valerolactone (207/163) and 5-(hydroxy-methoxyphenyl)-γ-valerolactone (221/162), are also shown to confirm metabolites.
