plant extract as antioxidant

Mar 30, 2020

Although the traditional synthetic antioxidants have relatively strong antioxidant capacity, they are potentially toxic for long-term consumption, and some even cause teratogenic and carcinogenic effects, so they are increasingly rejected by people; bee pollen is collected by bees from flowers Pollen grains, which contain flavonoids, vitamins, hormones, nucleic acids, enzymes and trace elements, have anti-aging effects and are good antioxidant foods. Experiment proves the antioxidant effects of Pueraria lobata, Eucommia ulmoides leaves, Lycium barbarum, Cotoneaster, Poria cocos, Schisandra chinensis, Ginkgo biloba, bamboo leaves, lemon, citrus and propolis.. Therefore, the selecting substances with antioxidant and free radical scavenging activity from natural products is of great significance to the food and pharmaceutical industries.


The mechanism of natural products to scavenge free radicals is very complex. Generally speaking, it is related to the rich antioxidant active substances in natural products. Through supplementing the highly active antioxidant ingredients contained in natural products (such as flavonoids, tannins, unsaturated, fatty acids, vitamins, etc.) to the to increase the body's antioxidant substances and prevent the formation of free radical chain reactions and further damage.

 According to reports, flavonoids and phenolic compounds all have the effect of scavenging free radicals. In addition, structural factors related to antioxidant activity, such as the number and position of phenolic hydroxyl groups the combination of monomers also contribute to removing free radicals . There is a certain relationship between the strength of free radicals, such as catechins and their oxides, which contain multiple free phenolic hydroxyl groups, have a strong ability to provide hydrogen protons, reduce highly oxidative free radicals, and terminate free radical chain reaction to achieve the purpose of scavenging free radicals.
