Supply Bayberry bark Extract Myricetin 98% 529-44-2 CAS NO.529-44-2

The bulk of the medicinal attributes are located in the bark. This is due to its high concentration of flavonoids and tannins. Myricitrin is the primary flavonoid.Although there are several species, Bayberry has been traced back to the Native American Indians where they used it for diarrhea, fever, uterine bleeding and tooth aches.

The colonists however did not focus on this herb's medicinal qualities but centered on its other properties for making candles, soaps and cosmetics.Each country that utilizes this plant for medicinal purposes has its own primary use for it.For example China favors it as an astringent and for the relief of pain, while Taiwan will recommend it for stomach disorders and diarrhea.Aside from its medicinal properties, bayberry is a beneficial ingredient in some cosmetics and is a favorite for candle makers.With its many potential benefits it should only be a matter of time until more extensive studies are conducted both in the medicinal and cosmetic fields.

1. Anti-oxidation; Myricetin is an inhibitor of cyclooxygenase 1 (COX-1), cyclooxygenase 2 (COX-2) and 5-lipoxygenase (5-LOX);

2. Antagonic action on platelet activating factor (PAF), demonstrating pharmacological actions such as anti-thrombus, anti-myocardia ischemia, improving the microcirculation and prophylaxis of artery cirrhosis;

3. Adjusting cholesterol level; In vitro research suggests that myricetin in high concentration is capable of modifying LDL cholesterol in a manner that enhances its uptake by white blood cells.

4. Decreasing blood sugar; It can be used as food additive for diabetics;

5. Protecting liver;

6. Anti-inflammation and anti-infection;

7. Acting as inhibitor of matrix metalloproteinase; It can be used for prevention and treatment of cardiovascular disease and tumor;

8. A good dyeing agent.

 

1.Reducing the levels of blood sugar:

Myricetin has a good effect of reducing the levels of blood sugar.

2.Anti-tumor:

Myricetin has effective restrain to cell proliferation of some tumor cells.

3.Affecting the activation and proliferation of lymphocyte:

Myricetin can restrain the expression of CD69 which is the early activatory sign of T cells.

4.Low the neurotoxicity:

Myricetin can protect the neuron by restraining the neurotoxicity caused by Glutamic acid. Then it can hold neurotrosis effectively.

5.Antioxidation:

Myricetin Play a vital role on many neurologic disease such as ischaemia and Alzheimer’s disease through oxidative stress. It can reduce production and toxicity of the β-amylase.

6.Antagonism of platelet activiation factor(PAF):

Myricetin can restrain the gathering of WRP and release of 52HT caused by PAF. It can also restrain the rising of Serum ionized calcium in the platelet caused by PAF.

7.Protecting the liver:

Myricetin has the strong inhibitory action of the rise of ALT and AST in the blood Serum. It can low the total bilirubin in the blood serum. So myricetin has the strong action of lowing the aminotransferase and jaundice.
