Extract Method

Polygonum cuspidatum, a traditional TCM herb, itself contains a small amount of resveratrol, but it contains up to about 3% polydatin. Which can turn to resveratrol after biological fermentation. Some scholars use rhizozyme bacteria to carry out liquid fermentation of the crude extract of polydatin to convert polydatin into resveratrol, with a conversion rate of 95.8%.

Resveratrol exists in the form of resveratrol glycosides in many plants, which can be hydrolyzed into resveratrol powder with help of enzyme. This method can reach higher outcome.
