In animal and human studies, greater green tea consumption and increased catechin intake are correlated with improvements in health and reduced disease risks, including:
To sum up, the efficient and sustained production of TFs required the high PPO activity and high concentration of catechin substrates; high POD activity would rapidly transfer TFs into TRs and TBs, which was adverse to the accumulation of TFs.
Furthermore, they demonstrate that catechin is effective in reverse diastolic dysfunction and could be useful for the troponin mutations-induced RCM.[15] In this study, application of large doses of catechin (50 mg*kg −1*day −1) was performed and it was effective in improving diastolic function and clinical symptoms.
Here, the enhancement of encapsulated catechin's antioxidant and metal chelation potential over free catechin would bring novelty to this study.
However, the relative amount of caffeine and gallate catechin against theanine was higher in standard Sencha than in Gyokuro.
In conjunction, the data from in vitro and in vivo studies suggest green tea catechins, in particularly EGCG, exert anti-obesity effects via several mechanisms including inhibition of adipocyte differentiation and proliferation, reduction of fat absorption and fat mass, tricylglycerides, free fatty acids and total cholesterol.
The four major polyphenolic catechins present in green tea include: ECG [(-)EpiCatechin-3-O-Gallate]; GCG [(-)GalloCatechin-3-O-Gallate]; EGC [(-)EpiGalloCatechin]; and EGCG [(-)EpiGalloCatechin-3-O-Gallate], the most abundant and biologically active green tea constituent.
The UV absorption spectra of the extract and standards when using methanol as solvent, they have shown peak maxima at 280 nm, (Table 5), indicating the presence of catechin and tannic acid.

Epigallocatechin gallate (EGCG) is the most abundant green tea catechin and is considered the most bioactive constituent that can reduce body weight by decreasing fat cell differentiation and proliferation.
