What's Polygonum Cuspidatum Extract Resveratrol?
Resveratrol is a natural ingredient with various biological activities, which is mainly extracted from the rhizomes and roots of Polygonum Cuspidatum. It has CIS and trans structures. It is brown (50%) to off-white(98%) powder with trans-resveratrol being the more bioavailable and absorbable. It is usually white to light yellow crystal powder, insoluble in water, but easily soluble in organic solvents such as ether, ethanol, acetone and ethyl acetate.
Resveratrol is widely used in the production of health products, such as resveratrol capsules, which are loved by consumers for enhancing immunity, antioxidant and so on. Resveratrol is added to skin care products, such as creams, serums, masks, etc., to improve the health of the skin. Resveratrol can be added as a food additive to wine, juice, beverages and other foods, which can not only increase the nutritional value of food, but also play a certain role in preservative preservation and extend the shelf life of food.
