(-)-GALLOCATECHIN Usage And Synthesis
Chemical PropertiesOff-White Solid
UsesAn antioxidant with free radical scavenging ability; a potential cancer chemopreventive agent. It inhibits the growth and adherence of P. gingivalis onto the buccal epithelial cells. An epimer of (-)- Epigallocatechin (E588940).
Uses(?)-Gallocatechin has been used as a reference standard:
  • for the identification of phenolic compounds present in Pineapple (Ananas comosus) using high-performance liquid chromatography (HPLC)
  • to evaluate the catechin profiles from Camellia sinensis green tea, white tea, and flower sample by high-performance liquid chromatography/photodiode array detection (RP-HPLC/PDAD) analysis
  • as a reference standard for the flavan-3-ols profiling muscadine grape hybrid varieties using high-performance liquid chromatography-quadrupole, time-of-flight, tandem mass spectrometry (HPLC-qTOF-MS/MS) analysis

UsesPolyphenolic compound from green tea. Possesses free-radical scavenging ability
DefinitionChEBI: (-)-gallocatechin is a a gallocatechin that has (2S,3R)-configuration. It has a role as an antioxidant, a radical scavenger and a metabolite. It is an enantiomer of a (+)-gallocatechin.
General DescriptionGallocatechin belongs to the catechin class of organic compounds and is one of the major components of green tea. The beneficial effects of catechins include anti-tumorigenic, anti-mutagenic, anti-pathogenic, and anti-oxidative properties.
Biochem/physiol Actions(?)-Gallocatechin (GC) exerts antioxidant properties by scavenging free radicals. It can also inhibit osteoclastgenesis. GC elicits antimutagenic activity in Escherichia coli against ultraviolet (UV)-induced mutation. It also displays an inhibitory effect on the growth and adherence of?Porphyromonas gingivalis?in the buccal epithelial cells.
