“…In this way, the antioxidant compounds minimize the oxidative stress and prevent the oxidative damage to food materials and living organisms. reducing, metal chelating, lipid reducing and free radical scavenging activities [24,[28][29][30]. These also possess antioxidant enzyme activities as these have been found to enhance the activities of some antioxidant enzymes including glutathione peroxidase, superoxide dismutase, catalase, heme oxygenase and ascorbate peroxidase [21,[31][32][33] ( Table 6).…”

The edible parts of Brassica plants are a rich source of phytochemical compounds which possess strong antioxidant potential. These plants contain a variety of phytochemical compound including phenolics, polyphenols, phenolic acids, flavonoids, carotenoids (zeaxanthin, lutein, β-carotene), alkaloids, phytosterols chlorophyll, glucosinolates, terpenoids, and glycosides. These plants possess strong antioxidant potential in terms of metal reducing, metal chelating, lipid reducing and free radical scavenging activities. These also have a positive effect on the activity of antioxidant enzymes such as glutathione peroxidase, superoxide dismutase, catalase, and ascorbate peroxidase. Among various species of genus Brassica studied for their phytochemical composition and antioxidant activity, Brassica oleracea leaves, florets and seeds have better phytochemical and antioxidant profile. Brassica juncea, Brassica napus, Brassica rapa and Brassica nigra are also the phytochemical and antioxidant rich species of genus Brassica. The phytochemical profile and antioxidant potential of Brassica plants make them the preferable candidates for nutritional and pharmaceutical applications.

“…Recent literature reports reveal that plant-based natural compounds of Brassica oleracea L. var. sabauda [47], red fruits teas [48], Salicornia herbacea L. [49], vegetables and agricultural by-products [50], ascorbic and humic acids [51], Raphanus sativus var. niger [52], green tea [53], and eugenol [54] display both antioxidant and prooxidant behaviours under certain circumstances.…”

Secondary bioactive compounds of endophytes are inevitable biomolecules of therapeutical importance. In the present study, secondary metabolites profiling of an endophytic bacterial strain, Acinetobacter baumannii, were explored using GC-MS study. Presence of antioxidant substances and antioxidant properties in chloroform (CHL), diethyl ether (DEE), and ethyl acetate (EA) crude extracts of the endophytic bacteria were studied. Total phenolic content (TPC), total flavonoid content (TFC), total antioxidant capacity (TAC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, and ferrous ion chelating assay were evaluated. A total of 74 compounds were identified from the GC-MS analysis of the EA extract representing mostly alkane compounds followed by phenols, carboxylic acids, aromatic heterocyclic compounds, ketones, aromatic esters, aromatic benzenes, and alkenes. Among the two phenolic compounds, namely, phenol, 2,4-bis(1,1-dimethylethyl)- and phenol, 3,5-bis(1,1-dimethylethyl)-, the former was found in abundance (11.56%) while the latter was found in smaller quantity (0.14%). Moreover, the endophytic bacteria was found to possess a number of metal ions including Fe(II) and Cu(II) as 1307.13 ± 2.35 ppb and 42.38 ± 0.352 ppb, respectively. The extracts exhibited concentration dependent antioxidant and prooxidant properties at high and low concentrations, respectively. The presence of phenolic compounds and metal ions was believed to play an important role in the antioxidant and prooxidant potentials of the extracts. Further studies are suggested for exploring the untapped resource of endophytic bacteria for the development of novel therapeutic agents.

“…They offer a higher total phenolic content and total flavonoids compared with seed extracts, which is correlated with its high antioxidant capacity [13]. These changes are due to a variety of biochemical processes that cause a different composition of primary and secondary metabolites, which in turn leads to an altered production of phenolic compounds [14].…”

Objective: Saturated blood levels of B vitamins have beneficial effects on various cellular processes by preventing oxidative stress, which is associated with accelerated aging processes and with the development of several chronic diseases. The aim of the present study was to determine the impact of the daily intake of a B vitamin complex to the antioxidative status in healthy adults. Methods: In a randomized, double-blind clinical trial a natural vitamin preparation (N) was compared to a synthetical (S) one. 30 subjects were allocated to either group N or group S. Blood was drawn from the subjects prior to the supplementation phase (T1), after the six-week supplementation phase (T2), and after a subsequent two-week wash-out phase (T3). The blood samples were analyzed for their total antioxidant capacity (TAC), total oxidant capacity (TOC), total polyphenol microtiter (PPm) and for the endogenous peroxidase activity (EPA). Results: In both groups TAC was enhanced after T2 (N: +26%; S: +6%), but reached significance only in group N (p < 0.05). TOC was reduced in both groups at T2 and decreased even further after T3. EPA increased at both, T2 (N: +29%; S: +41%), and T3 (N: +80%; S: +68%). A PPm decrease occurred in both groups. Conclusions: These results demonstrate that B vitamin additives might be helpful to decrease oxidative stress. Natural vitamins yielded a modestly stronger effect compared to manufactured ones.
