Total phenolic contents and antioxidant activities of various solvent extracts from whole wheat. and bran. Total phenolic content DPPH/RSA. Three solvent systems have been used to prepare the anti- oxidant extracts from whole wheat and its bran fraction. Antioxidant activities were tested using DPPH radical scavenging activity and total flavonoid content.

Total phenolic content in the 95% ethanol and 50% acetone fractions I-V were measured.. No signals of phenolics were detected in the fractions V of both 95% ethanol and 50%. Similarly, the fraction I of acetone eluent also exhibited highest total phenolic content (189.8 μgGAE/mL) and then decreased in the following fractions (fig. Since the phenolic content was not detected in the fraction V, 250 mL of eluent is sufficient enough to elute maximum phenolic compounds from the column..

Results: A genome-wide association study (GWAS) was conducted for total phenolic content (TPC), total flavonoid content (FLC) and antioxidant activity (AOA) in 67 cultivated and 156 Tibetan wild barley genotypes. The markers bPb-0572 and bPb-4531 were identified as the major QTLs controlling phenolic compounds in Tibetan wild barley. Conclusions: GWAS is an efficient tool for exploring the genetic architecture of phenolic compounds in the cultivated and Tibetan wild barleys.

The content of the dialysis bags was the. Bioaccessibility (BI%) was determined as described by Dantas et al. All experiments were performed in triplicates, and the resultsare expressed as mean ± standard deviation.The differences of the properties between J. The total phenolic and total flavonoid content values of the J. The total phenolic content (TPC) of the berries was found as mg GAE/g in dried berries and lower than the content determined by Miceli et al. Taviano et al.

There is also a high amount of gallic acid in the flowers. the results of the phenolic contents, the antioxidant strength of the root is significantly higher than that of the leaves and flowers.. According to the results given in Table 2, the highest phenolic content can be seen in the root and flower.. Although the essential oil content for similar Geranium species has been examined in the literature, the phenolic component content has not frequently been studied.

Total phenolic and flavonoid content. There is significant difference in phenolic content among S. Particularly, the phenolic content of ethyl acetate fraction was about 5 times higher than that of butanol fraction and about 9 times than that of n-hexane fraction.. However, the flavonoid content of all four fractions from roots extracts of S. Ethyl acetate fraction also contained significantly highest flavonoid content..

Table 3 indicates total phenolic content and antioxidant activity measured from exocarp layer and seed of pistachio genotypes.. Total phenolic content in both exocarp layer and seeds was signif- icantly different among studied genotypes.. The highest total phenolic content in exocarp layer samples was observed in G3 (35.64 mg GAEs/g) followed by G16 (35.02 mg GAEs/g) and G20 (32.51 mg GAEs/g) genotypes.

Total phenolic, flavonoid, color intensity and bitter acid content of the beer samples. Total phenolic content, flavonoid content, color intensity and bitter acid content of the samples are presented in Table 2. From the study, it was deduced that the use of oat malt in brewing of the beer had an obvious negative effect on the phenolic content. The extract content of individual beer samples was not measured.

There is a limited study asserting the reduction of phenolic content in animal-derived PH-treated plants (Horii et al., 2007), whereas there is intensive evidence that indicates increased phenolic content associated with PH treatment (Colla et al., 2015). In PH-treated soybean, for instance, phenolic content increased significantly, while it decreased in PH- treated tomato plants (Horii et al., 2007).

Application of sulfur (40 and 80 mM) improved tocopherol content in both maize varieties.. Sulfur also improved salt tolerance in the salt-sensitive variety (Pak Afgoi 2003) to some extent (Figure 2). Application of sulfur (40 and 80 mM) significantly increased total phenolic content at all salt levels. However, higher levels of sulfur (80 mM) improved total phenolic content to a much greater extent.

Our findings showed that the essential bioactive components unique to bitter melon (especially phenolic acids and flavonoids known to be antioxidants) are found in higher amounts in commercial products. In addition, the phenolic content of the unripe fruit was found to be higher than that of the ripe fruit, which is again compatible with literature results..

On the other hand, the mix of the three extracts (1:1:1) re- corded the phenolic content higher than each extract alone mg GAE/g). The obtained TPC in the present study was higher than that reported by Bamdad et al. On the other hand, the total phenolic content for sage was higher than the value described by Darwish et al. c PEM: plant extract mix.. Means in the same raw followed by different lower case letters are significantly different (p b 0.05)..

Effect of drying and cold storage treatments on total phenolic content, total flavonoid content, and antioxidant activity of P. drying and cold storage treatments. Effect of drying and cold storage treatments on color properties (L*, a*, b*, C* and h°) of P. Total phenolic content in storage at 4 °C was almost twice that of microwave drying.. The lowest values in terms of FRAP antioxidant activity were found in microwave drying and storage at 10 °C..
