Abstract
The profiles of phenolic compounds and antioxidant properties of dehulled foxtail millets were studied. Twenty-one phenolics were detected in the free fraction, including a series of nine hydroxycinnamic acid spermidines reported for the first time and three flavonoid C-glycosides of kaempferol and apigenin. Twenty-three phenolic acid derivatives were detected in the bound fraction with ferulic acid being the predominant phenolic acid, as well as four ferulic acid dimers (DFAs) reported for the first time in foxtail millet. Total phenolic contents (TPC) of free and bound fractions varied from 161.86 to 224.47 mg ferulic acid equivalent (FAE)/kg DW, 170.69 to 294.75 mg FAE/kg DW, respectively. Antioxidant activities, based on the DPPH, ABTS+ and ORAC assays, were determined for all extracts related to TPC. Dehulled foxtail millet contains a diverse profile of phenolic compounds potentially suitable for development of functional foods with unique antioxidant properties.Entities:
