The biological activity of resveratrol has been recognized all over the world, but there are still many problems in the research and development of resveratrol products. In terms of raw materials, the natural wild resources of resveratrol are scarce, which forms a great gap with the market demand. In terms of quality control, there are relatively few studies on the identification of the true attributes of Polygonum Cuspidatum extract raw materials, and a complete set of laws and regulations on resveratrol quality control have not been formulated, so there are some defects in management control. The content of resveratrol in grapes is very low, but it has become an important raw material of the most popular natural resveratrol health products because of its safety, non-toxic, long edible history, and better biological activity. The price of Polygonum Cuspidatum extracted from grapes is much higher than that of resveratrol extracted from Polygonum Cuspidatum. There are great differences in product prices. But Driven by market interests, Polygonum Cuspidatum extract from relatively cheap Polygonum Cuspidatum is counterfeited as expensive grape resveratrol and applied to various fields such as health products and food.
In this way, there will be great hidden dangers and trade disputes. We expect more factories to strengthen product research rather than fraud. Let’s maintain a scientific and rigorous attitude and pragmatic development so that trans-resveratrol has more space for healthy development.
