Synthetic Process Research and Development of Resveratrol

An industrially efficient process for manufacturing resveratrol (3,4',5-trihydroxystilbene) from 3,5-dihydroxylbenzoic acid in Wittig-Horner route was developed. The significant progress is embodied in improvement for reduction or oxidation process and mild reaction conditions with fewer environmental pollution, and especially the high quality product (≥ 99.0%, HPLC) with favourable yield (beyond 64%) were obtained.
