MedKoo CAT#: 530676

CAS#: 84650-60-2 (green tea extract)

Description: Green tea extract, also called Tea polyphenol, are a mixture of chemical compounds, such as flavanoids and tannins, found naturally in tea. These chemical compounds are believed to be beneficial to human health, and they are the basis of many claims made about the health benefits of tea. Polyphenols are powerful antioxidants, which can reduce the risk of developing coronary artery disease and a number of other health problems. The compounds found in tea have also been linked with cancer reduction. Note: this product is supplied in 50% ethanol solution with concentration 200mg/mL.

More Info: The composition of the tea leaves depends on a variety of factors, including climate, season, horticultural practices, and the type and age of the plant. The chemical composition of green tea is similar to that of the leaf. Green tea contains polyphenolic compounds, which include flavanols, flavandiols, flavonoids, and phenolic acids and account for 30% of the dry weight of green tea leaves. Most of the polyphenols in green tea are flavanols, commonly known as catechins; the major catechins in green tea are (2)-epicatechin, (2)-epicatechin-3-gallate, (2)-epigallocatechin, and (2)-epigallocatechin-3-gallate (EGCG). In black teas, the major polyphenols are theaflavin and thearubigin. Major chemical compositions in tea polyphenol: (-)-epicatechin (EC): (2R,3R)-2-(3,4-dihydroxyphenyl)chroman-3,5,7-triol (-)-epicatechin-3-gallate (ECG): (2R,3R)-2-(3,4-dihydroxyphenyl)-5,7-dihydroxychroman-3-yl 3,4,5-trihydroxybenzoate (-)-epigallocatechin (EGC): (2R,3R)-2-(3,4,5-trihydroxyphenyl)chroman-3,5,7-triol (-)-epigallocatechin-3-gallate (EGCG): (2R,3R)-5,7-dihydroxy-2-(3,4,5-trihydroxyphenyl)chroman-3-yl 3,4,5-trihydroxybenzoate

Safety Data Sheet (SDS):
Biological target: Biological target: Tea polyphenol exhibits biological activity including antioxidant and anti-cancer activities, inhibition of cell proliferation, induction of apoptosis, cell cycle arrest and modulation of carcinogen metabolism.
In vitro activity: Treatment with EGCG (the most bioactive polyphenol in green tea) for 24 h resulted in the inhibition of cell proliferation in a dosedependent manner. As shown in Figure 1, EGCG inhibited the growth of SW480, SW620, and LS411N cells with an IC50 of 74.6, 99.4, and 112.1 μg/mL at 24 h, respectively. Besides, the results showed that SW480 cells were more sensitive to EGCG than SW620 and LS411N cells (Figure 1).

In vivo activity: MRI examination showed that TP (tea polyphenol) treatment improved disc degeneration. Although rats in the saline degeneration group maintained the original height of the intervertebral space in the first week, the disc signal significantly decreased; however, TPtreated rats showed a high disc signal level in the first week. Although the signal was somewhat indistinct and dispersed compared to the signal observed in the control group, the overall situation was better than that of the degeneration group (saline). In the MRIs performed at the second and fourth weeks, it was observed that the discs in the degeneration group became “dark discs” with an obvious decreased height of the intervertebral space. Conversely, the discs in the TP group showed an obvious improvement and retained high signals; the signal of the disc did not go dark sharply, although the height of the intervertebral space continued to decrease.
