Article Synopsis
  • A study on the leaves of Lonicera henryi used liquid chromatography tandem mass spectrometry (LC-MS(n)) to analyze chlorogenic acids, revealing 31 compounds including 13 previously unreported ones.
  • The unique fragmentation patterns in negative ion mode MS spectra allowed for characterization at the regioisomeric level and helped distinguish between chlorogenic acids and their glycosides.
  • A new LC-MS(n) method was developed for rapid identification of these compounds in various plant materials, foods, and beverages.
