Myricetin

详情

Botany: Kingherbs is used from the Ampelopsis grossedentata, it is called Teng cha in China. Myricetin is consisting of *-hydroxyflavone backbone and 6 hydroxyl groups. Pure Myricetin mainly occurs in nature in the form of glycosides.
Function:
1. Clear the free radical;
2. Anti-oxidation;
3. Modify LDL cholesterol, improve heart health by preventing LDL oxidation and reducing the uptake of oxidized LDL by macrophages;
4. Diminish inflammation;
5. Anti-fungi/bacterium;
6. Preventing the forming of the thrombus,
7. Anti-tumour & cancer, antimutagenic, especially good for prostate cancer, leukemia, nasopharyngeal darcinoma/NPC, pancreatic cancer;
8. Protect liver;
9. Improve bone-health;
*0. Myricetin inhibits the uptake of methylglucose by adipocytes, reduces oxidative injury in diabetes related bone diseases and reduces glucose plasma level in diabetic rats;
*1. Myricetin inhibits ROS production caused by glutamate and reduces glutamate-induced activation of caspase*3. Myricetin restored dopamine level in laboratory animals with induced Parkinsonism. Myricetin may also inhibit beta-amyloid fibril formation in Alzheimer patients.
