3. Functions & Application


The main function of Yangmeisu (Myricetin):

1) Antioxidant effect: Myricetin is a strong antioxidant, and oxidative stress plays a key role in various neurological diseases including ischemia and senile dementia. Myricetin reduces the production and toxicity of β-amylase through conformational changes and can be used to calculate the progress of senile dementia.

2) Anti-tumor effect: Myricetin is an effective carcinogenic chemical control agent.

3) Reduce neurotoxicity: Myricetin can inhibit neurotoxicity caused by glutamate to protect neurons through different pathways, thus effectively preventing nerve damage.

4) Effects on lymphocyte activation and proliferation: Myricetin can inhibit the expression of CD69 in early activation of T cells and inhibit lymphocyte proliferation.

5) Antagonism of platelet activating factor (PAF): Myricetin inhibited PAF-induced WRP aggregation and 52HT release in a concentration-dependent manner in vitro. At the same time, it can significantly inhibit the increase of intraplate free calcium caused by PAF. Therefore, myricetin has anti-thrombotic, anti-myocardial ischemia, and improved microcirculation and other aspects of cardiovascular pharmacology.

6) Hypoglycemic effect: Myricetin has obvious hypoglycemic effect.

7) The role of liver protection and liver protection: Dihydromyricetin can significantly inhibit the increase of serum alanine aminotransferase (ALT) and aspartase aminotransferase (AST) activity and reduce serum total bilirubin, which has a significant drop. The role of enzyme yellowing.
