Abstract:

Desulpho-glucosinolates in Chinese kale were identified by high performance liquid chromatography-photodiode array-electrospray ionization (HPLC-PDA-ESI/MS) through analyzing properties of MS and PDA under both positive and negative ion modes. Eleven glucosinolates including 7 aliphatic glucosinolates and 4 indolyl glucosinolates in Chinese kale were identified based on ion fragmentations under both negative and positive ESI modes. Further analysis of PDA spectra revealed only one absorption peak for aliphatic desulpho-glucosinolates and two absorption peaks for indolyl desulpho-glucosinolates due to the structure diversity.

Key words: Chinese kale (Brassica alboglabra L.), desulpho-glucosinolate, HPLC, PDA, electrospray ionization-mass spectrometry (ESI/MS), absorption peak
