Scientists have successively detected Piceid from different plants such as grapes and peanuts, and the content is low, so the main source is currently Polygonum cuspidatum. Research shows that it contains a variety of bioactive components, including polydatin, resveratrol, emodin, etc., as well as flavonoids, tannins and polysaccharides. Among them, resveratrol and polydatin are the two most important active ingredients.
