Phytochemical Constituents and Antioxidant Enzyme Activity Profiles of Different Barley (Hordeum Vulgare L.) Cultivars at Different Developmental Stages

Abstract

Barley grass possesses high nutritional value and antioxidant properties. In this study, the phytochemical constituents and antioxidant enzyme activities in six cultivars of barley grass were explored at three developmental stages: tillering, jointing, and booting stages. Total chlorophyll (Chl t) and carotenoid (Car) content, chlorophyll a/b (Chl a/b) ratio, total nitrogen nutrition (TNN), and total soluble protein (TSP) content, and superoxide dismutase (SOD), peroxidase (POD), and polyphenol oxidase (PPO) activities were assayed. The results indicated that the cultivar × development interaction was significant and that developmental stage was the main factor affecting the parameters studied. Cultivars had a negligible effect on these parameters, which varied with the developmental stages. In the tillering stage, Chl t and Car content, TNN, and POD activity achieved their highest value; in the jointing stage, SOD activity peaked; in the booting stage, Chl a/b ratio, TSP content, and PPO activity showed their highest values. TNN showed a negative correlation with TSP. Compared with those in the jointing, Chl t, Car, TSP, TNN content, Chl a/b ratio, and POD and PPO activities increased in the booting and the tillering stages, whereas SOD activity decreased. The differences in phytochemical constituents and antioxidant enzyme activities in barley grass were mainly correlated with the developmental stages. The aim of this study was to demonstrate the influence of developmental stages of barley grass on its phytochemical profile and antioxidant activities. Our results will help understand the mechanism of action of barley grass and provide theoretical support for the therapeutic application of barley grass.

Antioxidant and antiglycation activities of traditional plants and identification of bioactive compounds from extracts of Hordeum vulgare by LC–MS and GC–MS

“…vulgare, also contains an appreciable amount of bioactive compounds such as bioflavonoids, which may have beneficial impacts on humans (Deng et al, 2020;Prasad, Thomas, Bharosre, & Mir, 2019).…”

Reclaimed Salt-Affected Soils Can Effectively Contribute to Carbon Sequestration and Food Grain Production: Evidence from Pakistan

“…Moreover, organic amendments have the potential to increase soil organism biomass and to benefit plant health by decomposing organic matter, cycling nutrients and improving the structure of the soil [69,70]. The decomposition and transformation of organic matter and nutrients in organically modified soils are driven by an increase in MBC as well as an increase in soil enzyme activity [71,72]. The primary reason for the increase in DHA is likely to be the increased supply of organic C in stressed saline soils [73].…”

Protective Effect of Wheat and Barley Grass Against the Acute Toxicological Effects of the Concurrent Administration of Excessive Heavy Metals in Drinking Water on the Rats Liver and Brain

“…Germinated wheat and barley reduced the MDA and NO levels in the liver tissues and stimulated the antioxidant activity compared with the water mixed with HMs group. Barley grass possesses antioxidant properties [76]. It is abundant in antioxidants (like saponarin, polyphenols, superoxide dismutase (SOD), lutonarin, chlorophyll, Se vitamins (pro-vitamin A, C, and E), and flavonoids) that overturn lipid peroxidation [77].…”
