Flavonoids Library	576 compounds
Flavonoids are an important class of natural products; particularly, they belong to a class of plant secondary metabolites having a polyphenolic structure, widely found in fruits, vegetables and certain beverages. Flavonoids can be subdivided into different subgroups depending on the carbon of the C ring on which the B ring is attached and the degree of unsaturation and oxidation of the C ring. These subgroups are: flavones, flavonols, flavanones, flavanonols, flavanols or catechins, anthocyanins and chalcones. Flavonoids are now considered as an indispensable component in a variety of nutraceutical, pharmaceutical, medicinal and cosmetic applications. This is attributed to their anti-oxidative, anti-inflammatory, anti-mutagenic and anti-carcinogenic properties coupled with their capacity to modulate key cellular enzyme function. Naturally occurring flavonoids are known to have biological activities for use as drugs, for example, in diseases like cancer, Alzheimer’s disease (AD), atherosclerosis, etc. MCE offers a unique collection of 576 natural flavonoid compounds which is a useful tool for drug discovery as an important source of lead compounds.

5-Methoxyresorcinol (Standard)	Phenols Polyphenols Endogenous metabolite Source Classification	Reference Standards Drug Intermediate
5-Methoxyresorcinol (Standard) is an analytical standard for 5-Methoxyresorcinol (HY-W015752). This product is intended for research and analytical applications. 5-Methoxyresorcinol is a model molecule for the A ring of flavonoids, specifically mimicking the chemical behavior of the resorcinol-type A ring in catechins. 5-Methoxyresorcinol exhibits very low tocopherol regeneration activity. 5-Methoxyresorcinol shows little inhibition of cholesteryl ester transfer protein (CETP).

3'-O-Methyl-(-)-epicatechin gallate 3′-M-ECG	Structural Classification Flavonoids Camellia sinensis (L.) O. Ktze. Plants Other Flavonoids Source Classification Theaceae	Drug Derivative
3'-O-Methyl-(-)-epicatechin gallate (3′-M-ECG) is a methylated Catechin (HY-N0898) derivative and is an antioxidant agent. 3'-O-Methyl-(-)-epicatechin gallate reduces oxygen consumption and prevents decreases in linoleic and α-linolenic acids to protect canola oil from lipid oxidation when heated .

HY-N13285

(-)-Epigallocatechin-4'-O-methylether (-)-EGC-4'-O-ME	Structural Classification Ouratea Aubl. Phenols Polyphenols Plants Source Classification	Drug Derivative
(-)-Epigallocatechin-4'-O-methylether ((-)-EGC-4'-O-ME) is an orally active natural phenolic catechin with antioxidant, free radical-scavenging and hepatoprotective activities. (-)-Epigallocatechin-4'-O-methylether interferes with radiation-induced free radical formation, scavenges DPPH free radicals, inhibits carbon tetrachloride-induced increases in serum GOT and GPT, suppresses carbon tetrachloride-induced TBA-RS formation, and counteracts carbon tetrachloride-induced hepatocyte toxicity. (-)-Epigallocatechin-4'-O-methylether binds specifically to human serum albumin. (-)-Epigallocatechin-4'-O-methylether can be used in studies related to liver injury .
