Analysis of glucosinolates from broccoli and other cruciferous vegetables by hydrophilic interaction liquid chromatography

While methods for the identification and quantification of total plant glucosinolate content typically utilize desulfation of glucosinolates followed by reversed-phase chromatography, the analysis of intact glucosinolates has been problematic. Hydrophilic interaction chromatography offers a novel method for analyzing intact glucosinolates and when performed along with ion-pair reversed-phase chromatography offers a powerful and complementary method for glucosinolate analysis.
