Isoflavonoid compositions, phenylalanine ammonia lyase (PAL) activity and antioxidant capacity were evaluated in chickpea (Cicer arietinum L.) sprouts germinated after soaking with different sodium selenite (Na2SeO3) concentrations (0, 1 and 2 mg/100 g seeds). Chickpea seeds were germinated during four days at 24 degrees C and the isoflavonoid profiles and concentrations evaluated by HPLC-UV daily during four days of germination. Eleven isoflavones and two pterocarpan phytoalexins forms were identified in sprouts, being malonylated formononetin glycoside, formononetin, isoformononetin glycoside and malonylated biochanin A glycoside the major compounds. Compared to untreated sprouts, total isoflavonoid, PAL activity and antioxidant capacity showed a remarkable increase of 83%, 56%, and 33%, respectively in chickpea sprouts that were treated with a high sodium selenite content (2 mg/100 g seeds). Results suggest that Se-enriched chickpea sprouts could represent a good source of dietary Se and as an upgraded source of isoflavonoids. (C) 2017 Elsevier Ltd. All rights reserved.
