A comprehensive profiling of polyphenols from five Brassica species microgreens was conducted using ultrahighperformance liquid chromatography photodiode array high-resolution multistage mass spectrometry (UHPLC-PDA-ESI/ HRMS n ). A total of 164 polyphenols including 30 anthocyanins, 105 flavonol glycosides, and 29 hydroxycinnamic acid and hydroxybenzoic acid derivatives were putatively identified.The putative identifications were based on UHPLC-HRMS n analysis using retention times, elution orders, UV−vis and high-resolution mass spectra, and an in-house polyphenol database as well as literature comparisons. This study showed that these five Brassica species microgreens could be considered as good sources of food polyphenols.
