Identification of the anthocyanins in the black carrot extracts by LC-MS/Q-TOF in positive ionisation mode. The anthocyanin profile is consistent with those previously published for ‘Deep Purple’ [2, 28, 37–39]. Theoretical and measured molecular masses are shown for the positive ion [M]+ and the aglycon
