Quantification of lignans in food using isotope dilution gas chromatography/mass spectrometry Institute of Tropical Medicine
The optimization and validation of a protocol for the quantification of six dietary lignans, i.e., secoisolariciresinol, matairesinol, lariciresinol, pinoresinol, medioresinol, and syringaresinol, in food are presented. The method incorporates isotope dilution to ensure correct accuracy and precision, introducing the utilization of individual stable C-13(3)-labeled lignans. To demonstrate the potential of this new method, preliminary results ...
