Preparation and estimation of antiradical properties of different extracts from powdered barley (Hordeum vulgare L.) grass




Key words: 

young barley grass extracts, antioxidant activity, total phenolic content, antiradical properties


The increased promotion of healthy lifestyle associated with prevention of civilization diseases contributes to development of interest in food rich in bioactive compounds. Young green leaves of barley are considered as abundant source of important microelements, provitamins, vitamins and natural antioxidants. The literature data have been shown that barley grass contains significant amounts of flavonoids, chlorophyll, folate, pantothenic acid, vitamins B1, B2, B6 and E. The aim of this study was to compare five solvent systems at ambient temperature for their extraction efficacies of antioxidants from powdered young barley grass. The used solvents were water (W), methanol (M), ethanol (E), 3:7 water – ethanol mixture (WE), and 2:1 water – propylene glycol mixture (WG). The total phenolic content and antiradical activity were determined.  The total phenolic content was significantly greatest for both 3:7 water – ethanol (5.03±0.03 mg GAE/g d.m.) and 2:1 water – propylene glycol (5.29±0.18 mg GAE/g d.m.) antioxidant extracts from powdered barley grass. These extract exhibit also the highest antiradical activity. Therefore 3:7 water – ethanol mixture and 2:1 water – propylene glycol mixture are the most recommended solvents to prepare antioxidant extracts from young barley grass.
