Source of Resveratrol 

Resveratrol was discovered as early as 1924 and was first isolated from the roots of Veratrum grandiflorum by the Japanese in 1940. In 1976, Res (resveratrol) was discovered in the leaves of grapes. It is an antitoxin secreted by plants in adversity or when encountering pathogenic damage. Its synthesis increases sharply when exposed to ultraviolet rays, mechanical damage and fungal infection. Therefore, Called phytoantibiotics (phytoalexin). Res has been found in more than 700 species of plants, including 72 species of plants in 31 genera and 12 families, with higher levels in human foods such as grapes, knotweed and peanuts.

Physical and chemical properties of Resveratrol 

Resveratrol (3-4'-5-trihydroxystilbene) is a non-flavonoid polyphenol compound whose chemical name is 3,4',5-trihydroxy-1,2-diphenylethylene (3,4 ',5-Stilbenetriol), the molecular formula is C14H12O3, and the molecular weight is 228.25. The appearance of pure resveratrol is white to light yellow powder, odorless, difficult to dissolve in water, easily soluble in organic solvents such as ether, chloroform, methanol, ethanol, acetone, ethyl acetate, etc., with a melting point of 253~255°C. Sublimation temperature is 261℃. It can appear red with alkaline solutions such as ammonia water, and can react with ferric chloride-potassium ferricyanide to develop color. This property can be used to identify resveratrol.

Extraction method of Resveratrol 

• Resveratrol enzymatic extraction

Resveratrol exists in the form of resveratrol glycosides in many plants. Resveratrol glycosides can be enzymatically decomposed into resveratrol, and then free resveratrol can be extracted. This method can achieve higher yields, so some researchers have adopted enzymatic hydrolysis to extract resveratrol. There are three sources of enzymes in enzymatic extraction: using plant autologous enzymes, adding external enzymes, and inoculating microorganisms to produce enzymes.

• Resveratrol microwave extraction

Microwave extraction is a method that is beneficial to extracting the active ingredients in plants because plant cells absorb microwave energy in the microwave field and the temperature rises rapidly, expands and ruptures. This method is commonly used in laboratory research.

• Resveratrol supercritical carbon dioxide extraction

Supercritical CO2 extraction is a process that uses CO2 fluid in a supercritical state as a solvent to extract or separate certain components in a mixture. Supercritical CO2 is characterized by its stable nature, non-toxicity, non-polluting of the environment, and strong Penetration and dissolution capabilities, as well as good transferability and fluidity.

Theanine that exists naturally is L-type. The pure product is white needle crystal with a melting point of 217°C to 218°C and a specific optical rotation [α]D20=0.7°. It is extremely soluble in water and insoluble in organic solvents such as ethanol and ether. The aqueous solution is slightly acidic, with a caramel aroma and a refreshing taste similar to MSG. The taste threshold is 0.06%.

The effects of Resveratrol

Resveratrol is a non-flavonoid polyphenol compound widely found in plant foods or medicines such as grape knotweed and peanuts, and belongs to the stilbene class. Its functions and functions are:

1. Antioxidant and anti-free radical effect: Resveratrol is a natural antioxidant. Its most prominent effect is to scavenge or inhibit the generation of free radicals, inhibit lipid peroxidation, and regulate the activity of antioxidant-related enzymes.

2. Anti-tumor effect: The anti-tumor effect of resveratrol is characterized by its inhibitory effect on the initial promotion and development of tumors. It can produce varying degrees of antagonistic effects on various tumor cells such as gastric cancer, breast cancer, liver cancer, and leukemia through various mechanisms.

3. Cardiovascular protection: Resveratrol can bind to estrogen receptors in the human body to regulate blood cholesterol levels and reduce the incidence of cardiovascular diseases. Moreover, resveratrol also has anti-platelet aggregation effects, which can prevent platelets from aggregating and forming blood clots to adhere to the blood vessel walls, thereby inhibiting and reducing the occurrence and development of cardiovascular diseases.

4. Estrogenic effects: Resveratrol has a similar structure to the estrogen diethylstilbestrol and can bind to estrogen receptors and play a role in estrogen signal transduction.

5. Others: Resveratrol also has many pharmacological effects such as enzyme inducer, preventing Alzheimer's disease, delaying aging, inhibiting fat synthesis, antibacterial, anti-inflammatory and radiation protection.
