摘要：

This study was performed to evaluate the phytochemical composition, in vitro antioxidant capacity, anti-hyperglycaemic and anti-inflammatory activities, and simulated gastrointestinal digestion of 7-day-old freeze-dried barley sprouts (BS), one hybrid and one nonhybrid variety: 'NS565' (BSNS) and 'Golozrni' (BSG), respectively. BSNS expressed significantly higher (P <= 0.05) content of total phenols, chlorophyll and carotenoids. Phenolic compounds were the most dominant bioactives in both BSNS and BSG (713.25 and 479.02 mg GAE 100 g(-1) DW, respectively). BSNS possessed significantly higher (P <= 0.05) antioxidant capacity, evaluated by DPPH and ABTS assays, and reducing power (IC50DPPH = 0.54 mg mL(-1); IC50ABTS = 0.79 mg mL(-1); RP0.5 = 9.35 mg mL(-1)). Antihyperglycaemic and anti-inflammatory activities of BSNS (IC50AHgA = 1.43 mg mL(-1); IC50AIA = 1.86 mg mL(-1)) were also significantly higher (P <= 0.05) than BSG (IC50AHgA = 1.97 mg mL(-1); IC50AIA = 4.40 mg mL(-1)). In vitro simulation of gastrointestinal digestion showed higher release of phenolic compounds in intestinal fluid than in gastric fluid.
