설명

일반 설명

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

애플리케이션

(−)-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

생화학적/생리학적 작용

(−)-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.
