Description

field of invention

[0001] The invention relates to the fields of organic chemistry and functional food chemistry, in particular, the invention relates to a new demethylation process synthesis method of resveratrol, a trihydroxystilbene functional food. Background technique

[0002] Chemical name of resveratrol: 3,5,4'-trihydroxy-1,2-stilbene, also known as 3,5,4'-trihydroxystilbene, English name: Resveratrol, CAS: [501-36 -0], molecular formula: C 14 h 12 o 3 , molecular weight: 228.25. It is a multifunctional health food that exists in various plants such as grapes, knotweed, cassia, and peanuts. Resveratrol has extremely strong antioxidant properties, can effectively eliminate free radicals, and inhibit various oxidation reactions that cause atherosclerosis and thrombosis, thereby significantly improving the function of human endothelial cells, thus playing an important role in the prevention and treatment of cardiovascular diseases. important role in disease. In 200...
