Resveratrol is widely distributed in plants

Resveratrol is widely distributed in plants. As of 2021, it has been found in more than 70 plants from 21 families, especially in Vitis, Ampelopsis, Polygonum, Arachis, Cassia, Sophora, Veratrum, Eucalyptus plants. Representative plants containing resveratrol include grapes, Polygonum cuspidatum, peanuts, cassia seed, etc. There is already a simple and mature chemical synthesis method for resveratrol with high product yield and low production cost, which is used for industrial large-scale preparation, making the acquisition of resveratrol no longer dependent on extraction and separation from plants. The synthesis process of resveratrol often uses the Wittig reaction to achieve the splicing of two benzene rings, with a yield of over 50%.
