Purpose of the Study:

  • To present a novel analytical method for the high-throughput, comprehensive, and quantitative fingerprinting of phenolic compounds.
  • To address the need for robust analytical tools in polyphenol research and food analysis.

Main Methods:

  • Reversed-phase ultrahigh-performance liquid chromatography (RP-UHPLC) coupled with a diode array detector (DAD) and mass spectrometry (MS).
  • Application of the method to analyze a broad spectrum of phenolic compounds and related metabolites in various food products.

Main Results:

  • The presented method enables high-throughput and comprehensive fingerprinting of diverse phenolic compounds.
  • Quantitative analysis of a wide range of phenolic metabolites was achieved with excellent analytical performance.

Conclusions:

  • The developed method is simple, cost-effective, and demonstrates excellent analytical performance.
