Phytonutrients refer to non-basic nutrients present in natural plants that are beneficial to the human body. Each plant contains different phytonutrients. At present, polyphenols, lycopene and other phytonutrients are found and used in health care. Select the most common “representatives” of phytonutrients to illustrate the role of phytonutrients in maintaining human health.
Coniferous cherry extract: Coniferous cherry is one of the most abundant natural sources of vitamin C known in the world. A small coniferous cherry can provide about 200 to 300 mg of vitamin C and is rich in flavonoids Phytonutrients; due to the presence of flavonoids, vitamin C in acerola can be better absorbed and utilized.
Ginkgo biloba extract: Ginkgo biloba leaves have been extracted into granules, liquid beverages and health medicines to enter the market, such as Amway Nutrilite Ginkgo Cistanche tablets, rich in Ginkgo biloba extract, DHA and Centella asiatica extract, can play an improvement The effect of memory.
Although plant phenols, polyphenols, flavonoids, terpenesand glucosides have many peculiar smells, they have antibacterial, anti-oxidation, improve body immunity, reduce the incidence of tumors and cardiovascular diseases, and effectively prevent certain diseases occur. These compounds are generally considered to be phytochemicals or phytonutrients. Phytonutrients are used in functional foods, and their research focuses on green leafy vegetables, mustard vegetables, citrus fruits, green tea, soybeans, and wine. As feed additives, phytonutrients have their unique advantages.
Alkaloids are widely distributed in plants in more than 100 families in the plant kingdom. Although the taste of alkaloids is bitter, it has special biological activities. For example, ephedrine in ephedra has the effect of relaxing bronchial smooth muscle, contracting blood vessels and exciting the central nervous system. Berberine is distributed in Coptis chinensis, Phellodendron chinense and other plants, and has antibacterial and anti-inflammatory properties. It is used to treat intestinal infections and dysentery.
2. Tea polyphenols
Tea polyphenols (TP) is the general term for polyphenol compounds in tea, including catechins, anthocyanins, flavonoids and phenolic acids. Tea polyphenols are light yellow to brown, slightly tea-like aqueous solution, off-white powdery solid or crystal, with bitter taste. Tea polyphenols have the functions of scavenging free radicals, antioxidant, anti-aging, anti-mutation, lowering blood lipids and cholesterol, and antibacterial.
As a feed additive, when tea polyphenols are added to the feed in vitro, the fat oxidation in the feed can be prevented. In the living body, tea phenol as an excellent donor of hydrogen or neutrons, tea polyphenols can not only protect antioxidant enzymes in the body, but also promote and regulate the activity of antioxidant enzymes in the body. Since free radical damage to biological systems is very serious, antioxidants can stabilize these highly active free radicals and ensure the integrity of cell structure and function. Therefore, antioxidants are very important for human and animal immune defense and health.
3. Soy Saponin
Saponins are the general term for oligosaccharides of sterols or triterpenoids. It is widely found in the plant kingdom and certain marine life. China's research on soybean saponins is mainly focused on its impact on human health, as feed additives have not been reported, but as a natural active substance, soybean saponins have many beneficial physiological effects. Such as anti-oxidation, anti-free radical effect, enhancement of immune regulatory function, anti-viral effect, anti-thrombotic effect, anti-tumor effect, etc. As a feed additive, soybean saponin may play an active role in the metabolism of animal nutrients, improving body immunity, improving digestive tract environment, and improving meat quality.
