Description

Cell separator based on extract anti-oxidant active ingredient
Technical Field
The invention relates to the technical field of cell separation, in particular to a cell separator based on extraction of antioxidant active ingredients.
Background
Antioxidation refers to the abbreviation of antioxidant free radicals. The human body continuously generates free radicals in the human body due to continuous contact with the outside, including respiration (oxidation reaction), external pollution, radiation irradiation and other factors. Scientific studies have shown that cancer, aging or other diseases are mostly associated with the production of excess free radicals. Research on antioxidation can effectively overcome the harm caused by the antioxidation, so the antioxidation is listed as one of the main research and development directions by health-care products and cosmetic enterprises, and is also one of the most important functional requirements of the market. Antioxidant is any substance that is present at low concentrations to effectively inhibit the oxidation of free radicals, either by acting directly on the free radicals or by indirectly consuming substances that readily form free radicals, preventing further reactions from occurring. The human body inevitably generates free radicals and also naturally generates antioxidant substances resisting the free radicals so as to counteract the oxidative attack of the free radicals on human cells. Research proves that the antioxidant system of the human body is a system which is comparable to the immune system and has perfect and complex functions, and the stronger the antioxidant capacity of the body, the healthier the body is, and the longer the life is. The antioxidant substances of the human body are synthesized by themselves and are also supplied by food. Enzymatic and non-enzymatic antioxidants play a crucial role in protecting peroxidative damage due to exercise. The supplement of the plant active selenium for enhancing the antioxidation is beneficial to reducing the generation of free radicals or accelerating the elimination of the free radicals by the sports organism so as to resist the side effect of the free radicals, thereby being beneficial to the health of general people and athletes, possibly delaying the occurrence of sports fatigue and accelerating the physical recovery, and the effect of taking the antioxidant by physical exercisers with large ages is better than that of physical exercisers with small ages.
