“…On the other hand, Bt176 and MS3/RF8 had significantly lower total phenoics content than their nontransgenic control. The data of total phenolics content in this study is in accordance with the data in literature (Simić et al, 2004, Vuorela et al, 2003.…”

Other than the targeted approach on compositional analysis, non-targeted approaches on genomics, proteomics and metabolomics are developing to search for unintended effects with respect to genetically modified (GM) food safety assessments. Antioxidant activity system was closely related with plant growth and reproduction as well as human health. This study was to investigate some other potential unintended effects from a range of primary and secondary metabolites by comparison of antioxidant activity system between six pairs of GMOs and their nontransgenic control. Antioxidant activity system was explored in total phenolics, unsaturated fatty acids and oxido-reductase activity analysis (including peroxidase (POD), polyphenol oxidase (PPO), catalase activity (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX) and glutathione reductase (GR)). The results from oxido-reductase activity analysis indicated significant differences (P < 0.05) between GMOs and their nontransgenic control, except for a few enzymatic activities of several GM crops. The data of total phenolics and unsaturated fatty acids also showed significant differences (P < 0.05) between GMOs and their nontransgenic control. However, no obvious differences occurred among all tested maize samples or canola samples.

“…After harvesting, grain weight was measured from 4x10 grains and expressed in g per grain. Then grains were milled and the content of total glutathione (GSH) was determined by the method of Sari Gorla et al (1993), water soluble phenolics were determined by the method of Simić et al (2004) and expressed in µg of 3-hydroxy-4-methoxycinnamic acid g-1 and yellow pigment (YP) was determined by the American Association of Cereal Chemists Method (AACC, 1995) and expressed in µg of β-carotene g -1 .…”

Content of some antioxidants in intercropped maize and soybean grain

Intercropping, as a combination of different crops at the same time and the same field, enables interaction of their roots, improving plant growth and stress tolerance, thus improving nutritional quality of produced grains. The investigation was aimed to examine the effect of different cropping systems: intercropping in combination with alternating rows and alternating strips of maize and soybean, as well as single cropping, combined with different fertilization regimes (conventional, application of organic fertilizer, bio-fertilizer and control) on the antioxidant content (glutathione [GSH], phenolics and yellow pigment [YP]) in red maize and black soybean grain. Black soybean is richer in antioxidants than red maize. Season expressed the highest influence on the level of GSH, phenolics and YP in maize and soybean, while cropping system and fertilization regime influenced GSH and phenolics.

“…GSH was determined from the same extract as P phy , by adding 0.2 M potassium phosphate buffer (pH = 8.0) and 10 mM DTNB (5.5′-dithio(2-nitrobenzoic acid)) and measuring the absorbance at 415 nm [24]. Free soluble phenolics were determined after 1 h extraction with bi-distilled water by method of Simić et al [25], based on a slightly modified Prussian blue method where 0.05M FeCl 3 in 0.1 M HCl and 0.008 M K 3 Fe(CN) 6 were added to sample solution. After 25 min, the absorbance of the reaction product was determined at 722 nm.…”

Background: Chickpea and peanut are two legume species not frequently used in human diets. Chickpea is rich in starch and proteins, while peanut is mainly a source of oils and proteins and they could be successfully used as protein sources in vegetarian diets. Seeds of 19 chickpea and 13 peanut landraces were colorimetrically analyzed in respect to antioxidant content (i.e., free soluble phenolics, total glutathione, and phytate). Oil and protein contents in grain were also determined. Results: Free soluble phenolics content varied in range from 520 to1,050 mg kg −1 in peanut and from 720 to 1,370 mg kg −1 in chickpea. Total glutathione content ranged from 1,495 to 2,365 mmol kg −1 in peanut and from 955 to 1,232 mmol kg −1 in chickpea. Relatively low content of phytic phosphorus was found in grain of both species, ranging from 2.5 to 4.5 g kg −1 in peanut and from 1.4 to 3.0 g kg −1 in chickpea, respectively. Considering the lack of data for phytate variability in Macedonian chickpea and peanut local landraces up to date, the observed high variation in phytic phosphorus content could represent the great basis for further breeding programs for phytate decrease in seeds of those genotypes. This is significant, since phytate is an important antinutrient which affects availability of mineral elements. Regression analysis revealed positive and highly significant interdependence between oil content and total glutathione in chickpea seeds, as well as between oil content and phytic phosphorus in peanut seeds. In chickpea, significant and negative correlation between oil and phytic phosphorus content was also observed. Conclusions: Results obtained indicated that chickpea genotypes with higher oil content could have increased nutritional value due to higher glutathione and lower phytate content observed. However, lower level of phytate content, along with higher level of soluble phenolics and total glutathione found in peanut seeds with lower oil content, indicated higher digestibility and increased antioxidant activity of those genotypes.
