Abstract

Eragrostis tef is an Ethiopian cereal with edible grain. There are two commercial teff varieties defined by the color of their seed; netch (white) and qey (red / brown). The recent interest in western countries for teff is based on their gluten-free composition and their appreciated nutritional advantages. The present work aims to characterize the polyphenolic profile of the Eragrostis tef grain. Therefore, the phenolic compounds present in the two varieties were identified and quantified by reverse phase high performance liquid chromatography with double detection by diode spectrophotometry and mass spectrometry (HPLC-DAD-MS). The revised literature describes the polyphenols in Eragrostis tef as non-flavonoids. In contrast, in this study flavones have been identified, in particular, luteolin and apigenin derivatives. The number of flavones tentatively identified in this study was 10, almost all of them identified in this work for the first time.
