Quercetin
Quercetin is a naturally occurring flavonol belonging to the polyphenolic subclass of flavonoids. It is characterized by a planar C15 flavonoid backbone with multiple hydroxyl substitutions and a C2–C3 double bond within the heterocyclic C-ring. This structural configuration contributes to its extended conjugation system and defined redox properties.
At LeafyLife, Quercetin is isolated through supercritical carbon dioxide extraction with controlled co-solvent optimization, followed by purification and standardization to achieve defined assay levels suitable for pharmaceutical and nutraceutical formulation systems.
Chemical Name: Quercetin
Molecular Formula: C15H10O7
Molecular Weight: 302.24 g/mol
Compound Class: Flavonol
Appearance: Yellow crystalline powder
Structural Features:
- Planar polyphenolic backbone
- C2–C3 double bond
- Multiple hydroxyl substitutions
The presence of the C2–C3 double bond differentiates it from dihydroquercetin and influences molecular planarity, electron distribution, and oxidative reactivity.
