Quantification of phenolic acid metabolites in humans by LC–MS: a structural and targeted metabolomics approach


Aim: Co-metabolism between a human host and the gastrointestinal microbiota generates many small phenolic molecules such as 3-hydroxy-3-(3-hydroxyphenyl) propanoic acid (3,3-HPHPA), which are reported to be elevated in schizophrenia and autism. Characterization of these chemicals, however, has been limited by analytic challenges. Methodology/results: We applied HPLC to separate and quantify over 50 analytes, including
