A recent report demonstrated that epigallocatechin gallate, a major polyphenolic catechin present in green tea, induces heme oxygenase-1 expression in cultured rat neurons, possibly by activation of the transcription factor Nrf2, and by this mechanism is able to protect against oxidative stress-induced cell death [ 17].
-Epigallocatechin-3-O-gallate (EGCG), which is the major green tea catechin present in the leaves, is believed to the compound most responsible for the health benefits attributed to tea.
a Caffeine and the four major catechins, EC, EGC, ECG, and EGCG, were detected.
The four major catechins (EC, EGC, ECG, and EGCG) shown in the HPLC profiles were identified as described in a previous study (Chen et al. 2014).
The HPLC profiles revealed the corresponding peaks to caffeine and the four major catechins including EC, ECG, EGC, and EGCG (Fig. 1a).
Epigallocatechin-3-gallate (EGCG), one of the major catechins in green tea, is a potential chemopreventive agent for various cancers.
Epigallocatechin gallate (EGCG) is the major catechin in tea.
The effects of epigallocatechin-3-gallate (EGCG), a major catechin in green tea, on human and mouse osteoblasts remain controversial.
The compound -epigallocatechin-3-gallate (EGCG) is the major catechin found in green tea [Camellia sinensis L. Ktze. (Theaceae)].
Catechins are the most vital secondary metabolites in tea plants which already demonstrated galloylated catechins presented stronger positive health benefit potential than that of nongalloylated catechins (Chen et al. 2014).
