Improved Method for Extraction and LC-MS Analysis of Pyrrolizidine Alkaloids and Their N-Oxides in Honey: Application to Echium vulgare Honeys

A method for analyzing honey samples was developed that enabled the simultaneous detection and identification of pyrrolizidine alkaloids and their N-oxides. Honey samples were treated with methanol or dilute sulfuric acid and then centrifuged to remove insoluble material. Subsequent strong cation ex...
