Description générale

(−)-Gallocatechin is a polyphenolic compound and one of the primary catechins present in green tea Camellia sinensis.[1]

Application

(−)-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)[2]
  • 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[3]
  • 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[4]

Actions biochimiques/physiologiques

(−)-Gallocatechin (GC) exerts antioxidant properties by scavenging free radicals.[5] It can also inhibit osteoclastgenesis.[6] GC elicits antimutagenic activity in Escherichia coli against ultraviolet (UV)-induced mutation.[7] It also displays an inhibitory effect on the growth and adherence of Porphyromonas gingivalis in the buccal epithelial cells.[8]

Autres remarques

Polyphenolic compound found in green tea. An epimer of (−)-epigallocatechin.

In this study, three tea catechins, epigallocatechin (EGC), gallocatechin (GC), and gallocatechin gallate (GCG), were investigated for their effects on bone metabolism. The effects of the tea catechins on bone formation were evaluated using cultured rat osteoblast-like osteosarcoma cell line

From the MeOH-extract of guava leaves, (+)-gallocatechin was isolated as a bio-antimutagenic compound against UV-induced mutation in Escherichia coli. This strengthens the evidence that phenolic compounds require three neighbouring-OH groups in order to possess this activity.
