Antioxidant activity of grain of einkorn (Triticum mono-coccum L.), emmer (Triticum dicoccum Schuebl [Schrank]) and spring wheat (Triticum aestivum L.) varieties

Abstract

Wheat and cereals generally are largely consumed worldwide and contribute significantly to antioxidant intake with beneficial health effects. In the precise two-year field experiments, two varieties of wheat einkorn, two varieties of emmer wheat and three varieties of spring wheat in 2008 and moreover further two spring wheat varieties, three einkorn varieties and three emmer wheat varieties in 2009, were evaluated for antioxidant activity (AOA) using 2,2-diphenyl-1-picrylhydrazyl assay (DPPH). The higher grain AOA was observed in emmer (215.4-257.6 mg Trolox/kg DM) and einkorn (149.8-255.8 mg Trolox/kg DM) varieties, while in spring varieties the AOA ranged between 195.8 and 210.0 mg Trolox/kg DM. A linear correlation between total polyphenols and AOA was determined (r = 0.739, P ≤ 0.05). Emmer and einkorn wheat varieties showed high AOA and can be promising sources of these nutritionally appreciated grain constituents.

Rheological and Technological Quality of Minor Wheat Species and Common Wheat

“…[14]. While antioxidant values in our findings increase from diploid (einkorn) to tetraploid, the reverse is true for Lachman's results.…”

“…This demonstrates a broad range of antioxidant content in wheat species. There were eight groups in which the means were not significantly different from one The findings of Lachman et al [14] showed that the antioxidant activity content of seven varieties ranged between 134.0 and 197.5 mg Trolox/kg DW. In this study, our results are approximately two times higher than these ones.…”

“…The used varieties were from the Gene Bank of the Crop Research Institute in Prague-Ruzyne, [14]. For the detailed evaluation of baking quality, Mixolab II.…”

“…The rate of enzymatic degradation The following methodology is based on the description in a paper by Lachman et al [14]. Laboratory analysis of composed finely ground wheat samples (ca 5.0 g) were weighed into 100 mL volumetric flasks and dissolved in methanol.…”

A comparison of macro- and microelement concentrations in the whole grain of four Triticum species

“…Lachman et al (2011) found that higher selenium content in grain is related to emmer (58.9-68.4 μg/kg DM) and einkorn (50.0-54.8 μg/kg DM) accessions and varieties; in spring varieties selenium content was lower and ranged from 29.8 to 39.9 μg/kg DM. Selenium content is important because some soils are poor in selenium that is a trace mineral essential to human with beneficial impact on health and possess also antioxidant activity (Lachman et al 2012). Contrary, some heavy metals are very toxic (Cd, Pb) and there is an effort to decrease their content in wheat by treatment with brassinosteroids (Kroutil et al 2010).…”
