Abstract

The fluorescence properties of anthocyanin pigments in extracts of red cabbage, Brassica oleracea, have been studied. The fluorescence spectra and fluorescence excitation spectra have been measured with absorption spectra of anthocyanins in extracts at pH 2 and pH 7. The results of the researches show that kinds of fluorescent anthocyanins (or/and other compounds) depend on pH conditions of red cabbage extracts. The properly chosen parameters of fluorescence measurement allow to distinguish spectrally two different fluorescent anthocyanin compounds in extract at pH 2 in comparison to pH 7, where three fluorescent compounds have been found.
