“…ABTS radical scavenging activity in cabbage was studied by other authors (Stratil et al, 2006;Kusznierewicz et al, 2008), they are indicated similar result between the ABTS and the DPPH activity. Also, according to our data (Table 2 and 3), the correlation between results obtained by the ABTS and DPPH assays is highly significant.…”

-Total phenol, flavonoid and antioxidant components of cabbage leaf samples derived from different cultivar were determined. Total phenol compound content showed the highest amount in methanol extracts from 'YR Howol' cultivar (11.72 ㎎/g), followed by 'Harutame' (10.66㎎/g), 'Winstar' (10.34 ㎎/g) and YR Hero (10.20 ㎎/g). The highest amount of total flavonoid content was observed from the methanol extracts of Harutame (5.39 ㎎/g), followed by Winstar (4.28 ㎎/g), Wialhowol (4.10 ㎎/g). The SOD enzyme activity showed a high activity of 'YR Hogeo' cultivar, and the cultivar of 'YR Howol' cultivar showed the lowest activity of SOD. The activity of CAT and APX showed higher values 'Ogane' and 'YR Hogeol' cultivars than the other cultivars. The POD activities showed relatively high values 'Ogane' and 'YR Howol' cultivars compared with other cultivars. The free radical (DPPH) scavenging activity showed lower IC50 values of 'Harutame' (15.71) and 'YR Howol' cultivar (16.88), however methanol extract of 'YR Hero' cultivar (22.49) being the highest. The extracts of all cabbage cultivars in the reaction solution of pH 1.2 could be decomposed nitrite more than 50%. Especially, the cultivar 'YR Hogeol' and 'Ogane' showed a relatively high nitrite scavenging activity for each 60.13% and 57.20% respectively. The IC50 values of antioxidant activity determined by ABTS were lower in 'Harutame' (17.04) and 'YR Howol' cultivar (17.97), and its results observed similar with values obtained from the same extracts by DPPH method. The result of this study suggests that the methanol extract of Brassica oleracea L. contains the high amount of phenolic and higher radical scavenging activities.

“…The total polyphenols of all studied raw vegetables (garlic, onions, peppers cabbages, lotus, and salad) were determined as previously described [105][106][107], and were in the quantitative range of 3.2 ± 0.3-15.6 ± 1.3 mg GAEؒg -1 DW. The antioxidant activities of the same vegetables as determined by FRAP assay, ABTS, DPPH, and CUPRAC varied significantly, and were in range of 6.2 ± 1.4-22.0 ± 1.9 μmol TEؒg -1 DW (DPPH values).…”

Abstract:The chemical diversity of natural antioxidants (AOXs) makes it difficult to separate, detect, and quantify individual antioxidants from a complex food/biological matrix. Moreover, the total antioxidant power is often more meaningful to evaluate health beneficial effects because of the cooperative action of individual antioxidant species. Currently, there is no single antioxidant assay for food labeling because of the lack of standard quantification methods. Antioxidant assays may be broadly classified as the electron transfer (ET)-and hydrogen atom transfer (HAT)-based assays. The results obtained are hardly comparable because of the different mechanisms, redox potentials, pH and solvent dependencies, etc. of various assays. This project will aid the identification and quantification of properties and mutual effects of antioxidants, bring a more rational basis to the classification of antioxidant assays with their constraints and challenges, and make the results more comparable and understandable. In this regard, the task group members convey their own experiences in various methods of antioxidants measurement.

“…The plants of Brassicaceae contain a number of compounds that can act as natural antioxidants (Raghavan, 2000). Several authors reported that also the chemical composition of Brassicaceae plants varies depending on the harvest time, growing conditions (Kusznierewicz et al, 2008) and stage of development (Björkman et al, 2011). The aim of the current research was to determine the content of phenolic compounds and antioxidant properties of horseradish leaves depending on harvest time.…”

A perennial herb horseradish (Armoracia rusticana L.) contains biologically active substances and cultivated in temperate regions of the world. The aim of the current research was to determine the content of phenolic compounds and antioxidant properties of horseradish leaves depending on the harvest time. For experiments horseradish leaves three years at six different times (during the period from May to October) were collected. Fresh plant material was extracted with ethanol using conventional extraction. For all extracts total phenolic content (TPC), total flavonoid content (TFC) and antioxidant activity (DPPH˙, ABTS˙+ scavenging activity, reducing power) were determined using a spectrophotometric methods. Results showed that content of phenolic compounds and antioxidant activity of horseradish leaves were significantly affected by harvest time. The highest TPC and ABTS˙+ scavenging activity was observed in the horseradish leaves collected in May, but the highest TFC and antioxidant activity (DPPH radical scavenging activity and reducing power) was observed in June. The content of phenolics compounds and antioxidant activity significantly decreased during post flowering stage and continues till October. Horseradish leaves contained considerable amount of phenolics compounds and natural antioxidants. In further experiments, use of horseradish leaves as natural antioxidants in different food matrixes should be studied.
