The effect of dihydromyricetin, how to eat dihydromyricetin

1) Add solid sodium hydroxide to the stirring tank, add water to prepare a solution of about 160g l under stirring, and then add HCB to the alkali solution according to the molar ratio of HCB to simple sodium hydroxide of 1 () under stirring, stir evenly and send it to the high-pressure hydrolysis kettle with a pump. When the stirring temperature rises to the pressure in the kettle, stop heating, due to the reaction exothermy, the temperature in the reaction kettle will automatically rise to 230, and the pressure in the kettle will reach. Hold the reaction for 230 minutes for 20min, and the hydrolysis is completed.

Then the material is discharged under pressure, cooled and crystallized, and filtered to obtain a flake solid sodium pentachlorophenol; [1] (Zhen 2) sodium pentachlorophenol was added to the reaction kettle, 31% hydrochloric acid was added for acidification under stirring, and the acidification temperature was kept at 80 90. After acidification, the product is washed, filtered, and dried to obtain the product. [2]

Summary. Dihydromyricetin is a wild woody vine (vine tea) extract of the genus Virgophyllaceae in the family Vitis vinifera, also known as dihydrobayberry quetin, dihydrobayberry flavonoids, snake grapetin, etc.

Dihydropoplar orange is a wild woody vine (vine tea) extract of the genus Snake in the grape family, also known as dihydrobayberry Qing finger quercetin, dihydroyuandan, bayberry flavonoids, snake grapevine, etc.

Dimyricetin is one of the main active ingredients of vine tea.

It has a variety of biological functions, such as scavenging free radicals, antioxidant, anti-hypertension, anti-thrombosis, anti-tumor, anti-inflammatory and other peculiar effects. <>

The main active ingredients are flavonoids.

Dihydromyricetin is a special flavonoid! It has the effects of relieving alcohol poisoning, preventing alcoholic liver and fatty liver, inhibiting the deterioration of liver cells, and reducing the incidence rate of liver cancer.

It is a good product to protect the liver and relieve hangover and sober up

Microherb studies have shown that the thermal stability of dihydromyricetin is good, but with the increase of temperature of more than 100 dihydromyricetin, an irreversible oxidation reaction will occur. Dihydromyricetin is stable under neutral and acidic conditions.

The epidermis of the leaves, roots and branches of bayberry is rich in tannins, anthocyanins and other flavonoids and polyphenols, vitamins, and potassium ions, all of which are essential minerals for maintaining normal fluid balance.

Class 1 flavonoids Modern research has shown that bayberry plants contain certain flavonoids, flavonoids are popular materials in today's health food research, they have a wide range of antioxidant properties, can remove waste from the body and keep people young. The main ingredient of bayberry flavonoids is bayberry flavonoids, which are hexahydroxyflavonoids. Studies have shown that it has antioxidant properties and cholesterol-lowering effects.

European countries, especially Mediterranean countries, have a large number of health functional foods**, which generally contain about 70% of bayberry flavonoids. 2 Anthocyanins: The red or purple color of bayberry fruit when ripe is due to a class of substances with a similar structure to flavonoids - anthocyanins.

Its structure is similar to that of flavonoids, and it also has good antioxidant function, regulating blood lipids and lowering cholesterol. The total amount of anthocyanins contained in bayberry fruit is approximate, and the anthocyanin content varies greatly among different varieties and maturity. 3 Other possible components and functions It has been reported in the literature that bayberry leaf extract has a good antibacterial effect, which can inhibit Staphylococcus aureus and Bacillus subtilis gram-positive bacteria, but has a poor effect on Escherichia coli-negative bacteria.

It has a good effect on common spoilage bacteria in food, such as Penicillium citrindicum, Penicillium arc and Aspergillus niger. Experiments showed that the total number of bacteria and the number of bacillus in pork, eggplant and tofu treated with bayberry leaf extract were much lower than those in foods not treated with bayberry leaf extract. These results indicated that bayberry leaf extract had a good inhibitory effect on bacteria and bacillus in food, and had obvious antiseptic effect.

Bayberry leaf extract has also been reported to have the function of inhibiting tumor growth. Amygdalin in bayberry pits has also been shown to have antitumor and anticancer effects.

Bayberry has a dyeing effect and is not easy to fade. China Textile Network recorded the relevant information of bayberry dyeing: bayberry bark, impregnation in warm water, boiling, adding an appropriate amount of sodium carbonate to the obtained liquid after treatment, adjusting to pH value 4-5, dyeing at 45 50, and then placing it in alum solution to obtain mordant solution, no mordant dyeing for light amber, gray matter mordant dyeing for yellow brown, tin salt mordant dyeing for yellow, ferrous salt mordant dyed for dark grass green, iron salt and lime combined with mordant dyeing for kelp color, copper salt mordant for tea yellow, chromium salt mordant for fresh beige.
