Antioxidants and Skin Care Aging is a natural process of life. However, retailers today are publicizing that their products can reduce or even eliminate the signs of aging. Many cosmetic companies advertise age-defying makeup, which they claim will erase the wrinkles on the skin and produce a newer, fresher look. The most recent age-defying product on the market is antioxidants. Claiming that their products will diminish the signs of aging, companies sell volumes of antioxidants to consumers
Antioxidants are substances that stable enough to prevent or retard the oxidation of easily oxidisable biomolecules such as lipids, proteins and DNA, thus preventing oxidative damage (Lobo et al. 2010). Antioxidants can be classified into two classes, according to their action, into primary or chain breaking antioxidants and secondary or preventative antioxidants. Primary antioxidants, when present in low concentration, can either delay or inhibit the lipid oxidation by reacting with a lipid radical
investigated. Folin-Ciocalteu phenol method estimated a total phenolic content of 22.415 GAE equivalents (µg GAE/mg sample). The presence of a high phenolic amount in the faba seeds indicates its potential as a good natural antioxidant. It has been recognized that flavonoids show antioxidant activity[24]. The total flavonoid content of the reconstituted extract was estimated by the aluminium chloride method and the results were expressed in µg of Catechin equivalents (CE) per mg of dry weight of the extract
Introduction Oxidative stress is essentially defined as the imbalance in the equilibrium of antioxidants systems in the human body. Oxidative damage in aerobic organisms can be caused by certain molecules known as reactive oxygen species (ROS). These reactive species are ones that cause oxidative damage in biomolecules. In order to maintain equilibrium of these substances, the human body has various endogenous antioxidants and phase 2 proteins which have evolved to defend against any harmful effects of ROS
Antioxidant Potency in Apples during Long Term Storage Introduction Apples are known to have many beneficial agents that may help prevent cardiovascular disease, cancer, and other chronic diseases (5). This is due to an important component in an apple called antioxidants. Antioxidants stabilize free radicals from damaging our healthy cells, protecting our DNA, and other genetic material. Antioxidants are not only present in apples but in foods such as; spices and herbs, certain beverages, legumes
know about antioxidants and belive in them as preventers against cell damage, which in the most severe case can cause cancer. Almost all nutritions contain a certain amount of antioxidant – both chemical and/or biological. To measure the activity and amount of the antioxidants present in a sample, some distinctive but easy assays have been established. This paper will give a short overview of the ORAC (oxygen radical absorbance cacpacity) assay and compare it with other antioxidant assays. Besides
because of reduced antioxidant defense system or the ROS increases beyond the capacity of antioxidants. The balance between oxidants and antioxidants is vital because oxidative stress can cause oxidative damages to N.A, lipids and proteins. The most important ROS are superoxide anion (O2−), singlet oxygen (O2), hydrogen peroxide (H2O2) and highly reactive hydroxyl radical (OH-). Whereas, antioxidant defense system is responsible to give protection against ROS. These antioxidants can scavenge and destroy
it is undesirable in high lipid or fat containing food products. Lipid oxidation is a major concern to the food industry due to the increasing emphasis on the use of polyunsaturated vegetable and fish oils, and discontinuing the use of synthetic antioxidants. Unsaturated fats are used extensively in the formulation of many food products and these are the most susceptible to oxidation. Lipid oxidation can lead to several changes to food products which affects shelf-life and consumer acceptance. These
ABSTRACT The study aimed to evaluate the effect Echinacea extract (E) on the testicular antioxidants function in normal rats or that subjected to anti-androgenic compound, cyproterone acetate (CA). Rats were divided into 5 groups treated daily via an oral tube for two intervals 2 and 4 weeks, 1st control, 2nd E (63mg/kg), 3rd CA (25mg/kg), 4th E+CA and 5th E as prophylactic one week before E+CA treatment. So CA used as a positive control compound with antiandrogenic activity with proposed testicular
vitamin E plays important roles as an antioxidant, in your immune system, in preventing heart disease and even in helping prevent cancer. As if this wasn’t enough, the research continues into other beneficial effects that vitamin E may have. It’s not particularly easy to come by however meaning if you want to get all the benefits you probably should consider a supplement to your diet. Vitamin E has many uses. Vitamin E plays an important role as an antioxidant. This means that it is important in
The phenolic compounds are the main component responsible for antioxidant activity, is mainly due to their redox properties, which can play an important role in absorbing and neutralizing free radicals, quenching singlet and triplet oxygen, or decomposing peroxides. Recently, phenolics or polyphenols have received considerable attention because of their physiological functions, including antioxidant, antimutagenic and antitumor activities. They have been reported to be a potential compound to combat
Introduction An antioxidant is any substance that significantly delays or inhibits the oxidation of a substrate (Young & Woodside, 2001). The physiological role of antioxidants is to prevent cellular damage arising as a consequence of chemical reactions involving free radicals. Free radicals are major contributors to degenerative diseases of aging, such as cancer, cardiovascular disease, cataracts, immune system decline, and brain dysfunction (Ames, et al., 1990) (Atoui, et al., 2005). Antioxidants have the

Its tender, crispy, dark-green leaves are favorite ingredients of chefs all around the planet. Spinach is so popular because of its taste, nutritional value and potential health benefits. Spinach has a high nutritional value and is extremely rich in antioxidants, especially when fresh, steamed, or quickly boiled. When preparing spinach, you should always cook
aluminum, minerals and trace elements. Tea Polyphenols and Catechins are Antioxidants Tea polyphenols are bioactive plant chemicals that include compounds known as catechins, which are believed to be responsible for many of the health benefits attributed to green tea. The most active and abundant catechin in green tea is known as epigallocatechin-3-gallate (EGCG), while epigallocatechin (ECG) is another. Both have high antioxidant activity – together, they act to neutralize harmful ‘free radicals’ in
metabolism and burns fat. The EGCG also called green tea extract plays an important role in weight control and fat reduction. It also helps in fat oxidation and simulating metabolism. The green tea leaves are rich in polyphenols that are natural antioxidants. These are also present in dark chocolate, red wine, fresh fruits and vegetables. When people green tea, the polyphenols will diluted with the water. Also, the tea should be served strong and bitter. When it comes to the polyphenols of the green
