What Is Resveratrol ?
Resveratrol is a natural compound found in certain plants, fruits, and red wine. It belongs to a group of compounds called polyphenols, which act as antioxidants and are known for their potential health benefits. Resveratrol is particularly abundant in the skin of red grapes and has been the subject of numerous studies due to its potential effects on various aspects of health.
Some research suggests that resveratrol may have potential benefits for heart health, as it may help support healthy blood vessels and circulation. Additionally, it has been studied for its potential anti-inflammatory and antioxidant properties, which could have implications for overall health and aging processes.
Resveratrol has also been investigated for its potential role in supporting brain health and cognitive function, as well as its effects on metabolism and potential benefits for weight management.
Physical and Chemical Properties of Resveratrol
Resveratrol (3-4'-5-trihydroxystilbene) is a non-flavonoid polyphenol compound. Its chemical name is 3,4',5-trihydroxy-1,2-diphenylethylene (3,4',5-trihydroxystilbene), its molecular formula is C14H12O3, and its molecular weight is 228.25.
The pure resveratrol appears as a white to light yellow powder, odorless, insoluble in water, and easily soluble in organic solvents such as ether, chloroform, methanol, ethanol, acetone, and ethyl acetate. The melting point is 253-255°C, and the sublimation temperature is 261°C. It can turn red with alkaline solutions such as ammonia water, and can react with ferric chloride-potassium ferrocyanide. This property can be used to identify resveratrol.
Natural resveratrol has two structures, cis and trans. It mainly exists in the trans conformation in nature. The two structures can be combined with glucose to form cis and trans resveratrol glycosides. Cis- and trans-resveratrol glycosides can release resveratrol under the action of glycosidase in the intestine. Under ultraviolet light, trans-resveratrol can be converted into cis-isomers.
Preparation Method
Natural plant extraction method
Grapes, knotweed and peanuts are used as raw materials to extract and separate crude resveratrol, and then purify it. The main crude extraction technologies include organic solvent extraction, alkaline extraction and enzyme extraction. New methods such as microwave-assisted extraction, CO2 supercritical extraction and ultrasonic-assisted extraction are also used. The purpose of purification is mainly to separate the cis- and trans-isomers of resveratrol and resveratrol from the crude resveratrol to obtain trans-resveratrol. Common purification methods include chromatography, silica gel column chromatography, thin layer chromatography, high performance liquid chromatography, etc.
Synthesis method
Since the content of resveratrol in plants is very low and the extraction cost is high, the use of chemical, biological, genetic engineering and other methods to obtain resveratrol has become an indispensable means in its development process. Perkin reaction, Hech reaction, and Witting-Hormer reaction are relatively mature chemical methods for synthesizing resveratrol, with yields of 55.2%, 70%, and 35.7% respectively. Genetic engineering technology is used to control or improve the biosynthesis pathway of resveratrol to obtain high-yield plant strains; methods such as using mutagenesis to select high-yield cell lines can increase the resveratrol yield by 1.5~3.0 times.
What Is The Benefit Of Resveratrol ?
Resveratrol has been the subject of research due to its potential health benefits. Some of the potential benefits of resveratrol include:
1.Anti-aging
In 2003, Harvard University professor David Sinclair and his team discovered that resveratrol can activate acetylase and increase the life span of yeast, which triggered an upsurge in anti-aging research on resveratrol. Howitz et al. found that resveratrol can serve as the strongest activator of silent information regulation 2 homolog1 (SIRT1), can simulate the anti-aging response of calorie restriction (CR), and participate in the regulation of the average life span of organisms. . CR is a strong inducer of SIRT1 and can increase the expression of SIRT1 in organs and tissues such as the brain, heart, intestine, kidney, muscle and fat. CR can cause physiological changes that delay aging and extend lifespan, the most significant of which can be extended by 50%. . Studies have confirmed that resveratrol can extend the life span of yeast, nematodes, fruit flies and lower fish.
2.Anti-tumor, anti-cancer
Resveratrol has significant inhibitory effects on various tumor cells such as mouse hepatocellular carcinoma, breast cancer, colon cancer, gastric cancer, and leukemia. Some scholars have confirmed that resveratrol has a significant inhibitory effect on melanoma cells through MTT method and flow cytometry.
There are reports that resveratrol can enhance cancer radiotherapy and effectively inhibit the effects of cancer stem cells. But so far, due to the complexity of resveratrol's anti-tumor mechanism, researchers have not yet reached a consensus on its mechanism of action.
3.Prevent and treat cardiovascular disease
Epidemiological studies have found that the "French paradox" phenomenon is that French people consume a large amount of fat on a daily basis, but the incidence and mortality of cardiovascular diseases are significantly lower than other European countries. This phenomenon may be related to their daily consumption of large amounts of wine. , and resveratrol may be its main active protective factor. Research shows that resveratrol can regulate blood cholesterol levels by binding to estrogen receptors in the human body, inhibit platelets from forming blood clots and adhesion to the blood vessel walls, thereby inhibiting and reducing the occurrence and development of cardiovascular disease, and reducing the risk of heart disease in the human body. Risk of vascular disease.
4.Antioxidant Support: Resveratrol acts as an antioxidant, helping to protect cells from oxidative damage caused by free radicals. This may have implications for overall health and aging processes.
