The relationship and difference between Quercetin and Rutin

Rutin is a flavonoid glycoside compound formed by combining quercetin and rutinose (a disaccharide composed of glucose and rhamnose). Quercetin can be obtained by acid-catalyzed hydrolysis of Rutin.
1. chemical structure
Rutin: Molecular formula is [C27H30O16•3H2O]. It is a flavonoid glycoside compound containing three molecules of crystal water.
Quercetin: Molecular formula is [C15H10O7•2H2O]. It is a flavonoid compound containing two molecules of crystalline water.
2. solubility
Rutin: It is poorly soluble in cold water (1: 10000), soluble in hot water (1: 200), easily soluble in alkali liquor, and is separated out after acidification.
Quercetin: It is difficult to dissolve in organic solvents with small polarity such as water and benzene, and soluble in organic solvents with large polarity such as methanol, ethyl acetate, acetone, etc.
3. physical properties
Rutin: Light yellow needle-like crystal. When containing trimolecular crystal water, the melting point is 174 - 178℃, and the melting point of anhydrous matter is 188 - 190℃.
Quercetin: Yellow crystal, with a melting point of 313~314℃ when containing two molecules of crystal water, and a melting point of 316℃ for anhydrous matter.
4. pharmacological effects
Rutin: It has the effect of regulating capillary permeability and reducing capillary fragility. It is clinically used as an auxiliary drug and capillary hemostatic drug for the treatment of hypertension.
Quercetin: It has many pharmacological effects such as anti-inflammation, anti-oxidation, anti-allergic, antibacterial, antiviral, etc.
