【 摘 要 】

Twenty-nine mature raw varieties of grain legume seeds (chickpeas, field peas, faba beans, common vetch and lupins) produced in Europe were investigated for their phenolic profile by means of high performance liquid chromatography coupled to diode array detection (HPLC-DAD). To the best of our knowledge, this study reported for the first time the phenolic composition of mature raw seeds of chickpea type Desi, field pea and common vetch. Phenolic acids were predominant compounds in chickpeas, field peas and common vetch compared to flavonoids, whereas the opposite was observed for lupin seeds. Yellow lupins presented the highest levels of total phenolic compounds followed by narrow-leafed lupins (in average 960 and 679 mg/kg, dry basis, respectively), whereas Kabuli chickpeas got the lowest ones (in average 47 mg/kg, dry basis). Principal component analysis revealed that flavones and total levels of phenolic compounds were responsible for nearly 51% of total data variability. (C) 2016 Elsevier Ltd. All rights reserved.
