Myricetin Powder Product Introduction
Myricetin powder is a polyhydroxy flavonol compound, which is a yellow needle-like crystal, molecular formula C15H10O8, relative molecular mass 318, melting point 324.0 ~ 325.5 ℃, UV spectrum has a maximum at 376.5 nm (Band I) and 254 nm (Band II). In absorption, the infrared spectrum shows hydroxyl (3575, 3380, 3255 cm﹣¹), conjugated carbon group (1646 cm﹣¹).
Double bond and aromatic ring carbon skeleton vibration (1662, 1550, 1505, 1454 cm﹣¹) absorption. The compound is soluble in methanol, ethanol, and acetone, slightly soluble in ethyl acetate, insoluble in water, petroleum ether (60 ~ 90 ℃), chloroform, toluene, and n-hexane, and has poor resistance to photolysis and is relatively stable under acidic conditions, and easily destroyed in neutral and alkaline environments.

Is myricetin powder good for you?
Of course yes, myricetin as a natural active ingredient has a wide range of pharmacological effects:
Anti-cardiovascular disease
The research on myricetin in anti-atherosclerosis, ischemia-reperfusion injury, myocardial infarction, and hypertension has made great progress. In vitro experiments have found that flavonol compounds such as myricetin can dose-dependently inhibit the glycation of low-density lipoprotein and reduce the electrophoretic migration of glycated low-density lipoprotein, so it can reduce the risk of arteriosclerosis in diabetic patients.
Fights bacterial and viral infections
Studies have shown that myricetin has different degrees of antibacterial effect on Corynebacterium, Staphylococcus, Streptococcus, and Bacillus subtilis. Resulting in protein inactivation and loss of function.
Myricetin also has anti-inflammatory, anti-allergic, antioxidant, and other pharmacological activities.
How does myricetin powder work?
Myricetin powder can significantly increase the AUC value of doxorubicin and the peak blood concentration of doxorubicin, and at the same time improve the absolute bioavailability of doxorubicin, but it has no significant effect on the pharmacokinetics of doxorubicin intravenous injection. Myricetin also increases the oral bioavailability of tamoxifen and carvedilol.
Maybe because doxorubicin, tamoxifen, and carvedilol are substrates of P-glycoprotein,Myricetin Powder enhances the absorption of drugs such as doxorubicin by inhibiting the efflux of P-glycoprotein, so It is speculated that it may be an inhibitor of P-glycoprotein. In addition, myricetin can also inhibit the cytochrome P450 3A enzyme in the small intestine and liver to reduce the first-pass effect, which may be another reason for increasing the oral absorption of drugs such as doxorubicin.
