Resveratrol was first discovered in 1939. It was first found in grapes in the 1970s. Later, it was found that it was also found in Polygonum cuspidatum, peanut, mulberry and other plants. Natural resveratrol is a natural active ingredient. It can be distributed and biosynthesis in plants (such as Polygonum cuspidatum) in free state (CIS and trans) and glycoside bound state (CIS and trans), and both have antioxidant efficacy. Among them, the biological activity of trans isomer is stronger than CIS, and it is an important plant antitoxin in grapes. People have conducted extensive research on its natural resources, and resveratrol has been found in at least 72 species of plants in 21 families and 31 genera, such as grapevine and Ampelopsis of grapevine family, groundnut, cassia and Sophora of legume, Veratrum of lily family, eucalyptus of myrtle family, Polygonum of Polygonaceae, etc. Many plants containing resveratrol are common medicinal plants, such as cassia, resveratrol, Polygonum cuspidatum, etc. some are food. For example, the content of resveratrol in grape and grape skin is the highest, up to 50 ~ 100mg / kg.
In 1980s, WHO survey found that although the French prefer high fat foods such as cheese, the incidence rate and mortality rate of coronary heart disease are lower than those of other western countries, probably due to the fact that the French often drink wine containing resveratrol. Since then, Polygonum Cuspidatum Extract Resveratrol has attracted much attention. Resveratrol is in great demand in the market. Due to its low content in plants and high extraction cost, chemical synthesis of resveratrol has become the main means of its development.
Polygonum Cuspidatum Extract Resveratrol is a natural antioxidant, which can reduce blood viscosity, inhibit platelet coagulation and vasodilation, maintain smooth blood flow, prevent the occurrence and development of cancer, and has the preventive and therapeutic effects of anti atherosclerosis, coronary heart disease, ischemic heart disease and hyperlipidemia. Tumor suppressor also has estrogen like effect and can be used to treat breast cancer and other diseases.
In the 1990s, Chinese scientists and technicians continued to deepen the research on resveratrol and revealed its pharmacological effects: inhibiting abnormal platelet aggregation, preventing myocardial tamponade and cerebral embolism, protecting the anoxic heart, controlling and reducing weight for obese people, and effectively recovering the decline of cardiac output caused by burn or hemorrhagic shock, It can dilate arteries and improve microcirculation.
