BACKGROUND A pandemic is when an infectious disease occurs in different parts of the world simultaneously and quickly spreads from person to person. The pandemic of the 21st century in the entire world is infection with the coronavirus. India now has the world's second-largest number of confirmed cases, next to US, following a recent increase in recorded infections. In case of serious corona infections, the out-ofcontrol immune system ultimately causes the patients' lungs to stop supplying oxygen to the body leading to respiratory failure. In some cases, the malfunctioning immune response in Covid-19 patients can drive the rapid decline in lung function. Symptoms of Covid-19, such as flu (influenza infection) similar to cold, can be avoided or mitigated and are mostly managed by combining a balanced diet with exercise and addition of antioxidants; the most common antioxidant is vitamin C in some form like raw or ripe fruits and vegetables is preferred and supplementations are also advised. Ascorbic acid is best known for its antioxidant properties and can scavenge damaging reactive oxygen species, thus protecting the body's cells and tissues from oxidative harm and dysfunction. However, vitamins also have many other significant body functions, many of which are known to promote good immune function. Vitamin C levels may be reduced during infection, and the demand for vitamin C enhances with the severity of the infection. Consequently, a possible antioxidant therapy may be suggested to get relief from the Covid-19 respiratory infection. An effective immune response relies on an appropriate diet and natural antioxidants, to hold infection at bay. KEY WORDS Natural Antioxidants, Vitamin C, Immunity, Covid-19, Pandemic

Oxidative stress is a result of disruption in the balance between antioxidants and pro-oxidants in which subsequently impacting on redox signaling, causing cell and tissue damages. It leads to a range of medical conditions including inflammation, skin aging, impaired wound healing, chronic diseases and cancers but these conditions can be managed properly with the aid of antioxidants. This review features various studies to provide an overview on how Carica papaya help counteract oxidative stress via various mechanisms of action closely related to its antioxidant properties and eventually improving the management of various oxidative stress-related health conditions. Carica papaya is a topical plant species discovered to contain high amounts of natural antioxidants that can usually be found in their leaves, fruits and seeds. It contains various chemical compounds demonstrate significant antioxidant properties including caffeic acid, myricetin, rutin, quercetin, α-tocopherol, papain, benzyl isothiocyanate (BiTC), and kaempferol. Therefore, it can counteract pro-oxidants via a number of signaling pathways that either promote the expression of antioxidant enzymes or reduce ROS production. These signaling pathways activate the antioxidant defense mechanisms that protect the body against both intrinsic and extrinsic oxidative stress. To conclude, Carica papaya can be incorporated into medications or supplements to help manage the health conditions driven by oxidative stress and further studies are needed to investigate the potential of its chemical components to manage various chronic diseases.

Abstract Phenolic compounds are natural antioxidants and can be found with abundance in fruits and vegetables. One of the first methods created for analyzing phenolic compounds was the Folin-Denis method; and hereafter, the Folin Ciocalteu method was developed and recently, one of the most recent method is the Fast Blue. Due to the importance of these compounds in food, this work aimed to determine the total phenolic compounds in three fruits, such as: Passion Fruit, “Palmer” mango and “Pera” orange. In addition, these fruits were analyzed through three different determination methods. Furthermore, the content of vitamin C, soluble solids, titratable acidity and pH of these fruits were evaluated. Based on the results, it was verified that there was no difference among the values of vitamin C, soluble solids and TA in relation to those found in the literature. When comparing the three methods (Fast Blue BB, Folin-Ciocalteu Reagent and Folin-Denis Reagent), the results showed a difference in the phenolic compounds that may be related to the distinct reagents used in each method and its different action.

Background: In recent years, it has become more evident that oxidative stress is involved in the development of cardiovascular disease. Indeed, reactive oxygen species seems to be the common mechanism for endothelial dysfunction, vascular inflammation and arterial stiffness, resulting in a blood pressure increase and early vascular aging. Methods: This review presents the potential role of antioxidant nutrients and exercise for cardiovascular protection. Results: Flavonoids, vitamins and minerals present in some fruits and foliage are considered natural antioxidants. In fact, fruits and vegetables contain large amounts of antioxidants. Several clinical trials have extensively studied vitamin E, beta-carotene, vitamin C, polyphenols, plus selenium and zinc. In addition, many authors have been carried out clinical trials to evaluate the mechanisms of oxidative stress attenuation after exercise. Exercise responses may vary according to the Frequency, Intensity, Time and Type (FITT) principle, making it difficult to obtain a consensus concerning the exercise properties and redox status. High-intensity interval training (HIIT) has been reported as an efficient option for metabolic adaptations in a short time. Aerobic exercises must be performed at least three times a week, for two months or more, using moderate to vigorous intensity to promote a positive effect on oxidative stress and vascular function. Conclusion: The recognition of appropriate nutrients and exercise with antioxidant properties may be an important supportive approach to impair early vascular aging and to prevent cardiovascular disease.

In recent years, natural antioxidants are often investigate because of synthetic antioxidants have an adverse effect on human health. Scientific research in the food industry focused on the search for natural antioxidants that would be similarly effective to synthetic antioxidants. For this purpose, commonly known and used natural compounds (e.g. carotenoids), spices and herbs particularly rich in chemical compounds with strong antioxidant properties (e.g. rosemary, thyme, sage, oregano, garlic, cloves) as well as green tea extracts, fruit extracts (e.g. plums, apricots, cranberries) are used. The addition of natural polyphenols not only prolongs the durability of food products, but also protects the body against oxidative damage. Epidemiological studies show a correlation between the consumption of polyphenol-rich products and a reduction in the risk of developing civilization diseases, including heart diseases.

Radicals produced naturally in the body, can cause various diseases when present in large quantities. High levels of free radical compounds showed low antioxidant activity that leads to degeneration of the body cells, metabolic disorder, decreased immune response that trigger the emergence of a variety of degenerative diseases. Need extra antioxidants from outside the body in order to help prevent the adverse effects of free radicals, such as antioxidants derived from plants used as cooking ingredients or food ingredients. There are some herbal plants that are a source of natural antioxidants , which are also used as a spice, such as turmeric (Curcuma domestica), ginger (Zingiber offcinale), nutmeg (Myristica fragrans), paprika (Capsicum annum), lemongrass (Cymbopogon citratus), galangal (Alpinia galangal), onion (Allium cepa) and garlic (Allium sativum).

Antioxidants are, no doubt, an essential part of an optimal health and even traditional doctors support the importance of an appropriate contribution of antioxidants taken through food. Antioxidants are a category of molecules able to inhibit the oxidation of other molecules. The body distributes various nutrients in the body due to their antioxidant properties and also factory antioxidant enzymes to keep under control the reaction in the chain of free radicals. Some antioxidants are produced by the body, but others don't. In addition, the body's natural ability to produce antioxidants decreases with age. Antioxidants play a significant role for health as it may influence the aging by fighting free radicals. There are antioxidants which can’t be produced in the human body, and to be taken through antioxidant-rich foods, or supplements powerful antioxidant. The paper aims to present some natural sources of oxidants that can be obtained through diet.

Over the past several years, natural antioxidants have attracted considerable interest as potential treatment for a wide variety of disease states, including cancer and other causes e.g. chronic inflammatory diseases and aging. Therefore, plant derived antioxidants are now receiving a special attention as they possess good antioxidant properties and hence a worldwide trend towards the use of natural phytochemicals present in fruits and vegetables have been reported. Numerous epidemiological studies indicate that consumption of cruciferous vegetables is associated with prevention of cardiovascular diseases and reduced incidence of cancers of the gastrointestinal tract and other sites. The substances that seem to be responsible for these properties are phenolic compounds (phenolic acids, flavonoids, polyphenols etc.) and sulphur-containing organic compound glucosinolates and their derived products. The present review focuses on the health promoting effects of phytochemicals and their beneficial bioactivities in Brassicaceae.

The effect of fenugreek and lingonberry supplements, containing natural antioxidants and a lot of important nutrition components, on the chemical composition and antioxidant content of flour mixture based on whole oat flour were investigated. Oat flour was produced using hydrothermal treatment, which included intensive moistening of the grain in the vacuum unit, standing, and drying. In addition to whole oat flour, the highgrade wheat flour, dry wheat gluten, and fenugreek seed powder or dried lingonberry powder were added to the flour composite mixture. The chemical composition of raw material and flour composite such as protein, carbohydrates, fat, and moisture was determined. Besides, antioxidant components, like Vitamin C and flavonoids in raw material and flour composites were investigated. From results, it has been established that adding fenugreek seed powder and dried lingonberry powder to flour composite based on oat flour leads to significant enhancing in the chemical composition and antioxidant compounds: the addition of the fenugreek seed powder led to the increase of protein content in the flour composite. Furthermore, adding dried lingonberry powder and fenugreek seed powder led to a slight effect on carbohydrates. The addition of fenugreek seed powder has the greatest effect on the content of flavonoids. In addition, vitamin C was significantly increased by the addition of lingonberry. According to, the results of our research can recommend the addition of fenugreek seed powder and lingonberry to oatwheat flour composite leading to improvement of its nutritional and antioxidant properties.
