The levels of all of the metabolites were determined after 10 days. Trace levels of anisic acid, veratric acid, trans-cinnamic acid, 4-hydroxybenzoic acid, phenylpyruvic acid, α-hydroxyphenylpropionic acid, β-hydroxyphenylpropionic acid, phenylacetaldehyde, β-phenylethanol, mandelic acid, benzoylformic acid, phenylacetic acid, and cinnamaldehyde were also found by GC-MS.
