During the space flight, the high-energy radiation in the universe may cause a number of health-relative problems such as the increased risk of cancer induction in astronauts. Recent studies have shown that a diet rich in antioxidants can mitigate the harmful effects of the radiation with high energy and particle charge during long-term space flight. Therefore, planting the vegetables rich in a...

considering the possibility of the harmful side effects of synthetic antioxidants, it is necessary to substitute the synthetic antioxidants by the natural ones, the antioxidants that have been consumed by man for years. the mango seeds were washed and air dried and the kernels were removed manually from the seeds. mango seed kernel oil was extracted by hexane using soxhlet extraction apparatus....

Antioxidants are substances that prevent oxidation of other compounds or neutralize free radicals. Spices and herbs are rich sources of antioxidants. They have been used in food and beverages to enhance flavor, aroma and color. Due to their excellent antioxidant activity, spices and herbs have also been used to treat some diseases. In this review article, the chemical composition and antioxidan...

Antioxidant capacities of 56 selected Chinese medicinal plants were evaluated using the Trolox equivalent antioxidant capacity (TEAC) and ferric reducing antioxidant power (FRAP) assays, and their total phenolic content was measured by the Folin-Ciocalteu method. The strong correlation between TEAC value and FRAP value suggested that the antioxidants in these plants possess free radical scaveng...

The levels of enzymic and non enzymic antioxidants were determined in Ehrlich’s Lymphoma Ascite (ELA) transplanted Swiss albino mice treated with the protein fraction of Cynodon dactylon (Cdpf). ELA induced mice showed significant decrease in the level of enzymic antioxidants like catalase (73.43 to 55.03), superoxide dismutase (4.49 to2.47) and glutathione peroxidase (48.48 to 36.98) in units/...

One of the biochemical pathways affected by aging in all organisms is protein synthesis. Previous reports from our laboratory have indicated that the elongation step is specially affected by aging as a consequence of alterations in elongation factor-2 (eEF-2). In the present work, we studied in vitro the effectiveness of several individual nutritional antioxidants in protecting the levels of he...

Antioxidant compounds in food play an important role as a healthprotecting factor. Scientific evidence suggests that antioxidants reduce the risk for chronic diseases including cancer and heart disease. Primary sources of naturally occurring antioxidants are whole grains, fruits and vegetables. Plant sourced food antioxidants like vitamin C, vitamin E, carotenes, phenolic acids, phytate and phy...

Natural antioxidants are abundant in food and medicinal plants. These natural antioxidants, particularly polyphenols carotenoids, have numerous biological effects, including anti-inflammatory, anti-aging, anti-atherosclerosis, anticancer properties. To examine potential cancer prevention agent sources advance their utilization useful varieties, drugs, added substances, it is fundamental for sep...

Aim: Reactive oxygen species induce oxidative stress that may contribute to endothelial dysfunction. In addition to endogen antioxidants, adding antioxidants to diet has been used to reduce oxidative-stress-induced endothelial dysfunction. Resveratrol is a natural phytoalexin which has many eff ects including antioxidant activity. Th e aim of this study was to investigate whether resveratrol co...
