What is Green Tea Egcg Extract?

A dipping method was developed to extract the catechins (Green Tea Egcg Extract) and alkaloids (caffeine) from green tea (Korea) and black tea (Sri Lanka). The effects of the solvent composition (water vs. ethanol), extraction time, temperatures, and solvent pH on the amount of catechins (EGCG) and alkaloids (caffeine) extracted from green and black tea were investigated. Reversedphase high-performance liquid chromatography (RP-HPLC) was used to analyze the catechins (EGCG) and alkaloids (caffeine) extracted. The content of EGCG and caffeine in green tea extracts was in the range of 2.04∼0.30 and 10.22∼0.85 mg/g, respectively.

 The amount of Green Tea Egcg Extract and caffeine in black tea extracts was in the range of 0.32∼0.24 and 5.26∼1.01 mg/g, respectively. The amount of caffeine extracted from green and black tea was greater than the amount of egcg extract green tea. Pure water is the best solvent for extracting EGCG and caffeine from green tea. The amount of caffeine extracted from green and black tea increased as the temperature, extraction time, and hydrogen ion concentration of the solvent increased. Although the amount of egcg green tea leaf extract extracted from green tea increased as the temperature increased, the amount of EGCG extracted from black tea was not affected by temperature. The extraction of EGCG from both green and black tea was not affected by the hydrogen ion concentration of the solvent.

Active ingredients of green tea extract:

Polyphenol, 4% to 6% of epicatechin (L-EC), 6% to 8% of gallocatechin (DL-EC), 10% to 15% of epigallocatechin (L-EGC), 50% ~60% epigallocatechin gallate (L-ECG), and 8% to 10% caffeine.

Green Tea Egcg Extract Benefits:

1. Prooxidant Effects and Activity of EGCG

Cancer is one of the most common and life-threatening diseases occurring among humankind. Green tea egcg extract, as a natural product, has drawn a great deal of attention from both the scientific community and the general public. Indeed, EGCG has shown both prophylactic and therapeutic efficacy in multiple human cancers. Several mechanisms have been proposed to account for the inhibitory action of EGCG against cancer formation and growth. The prooxidant effects of EGCG were thought to be potential mechanisms for action.

2. Prooxidant and Antiobesity Effects of EGCG

Obesity is a metabolic disease characterized by abnormal or excessive fat accumulation. It is generally associated with an increased risk of chronic diseases, including diabetes, hypertension, and dyslipidemia [10]. A large and growing body of studies has investigated the antiobesity effects of egcg extract green tea in cellular and animal experiments and the underlying mechanisms.

3. Prooxidant and Effects of EGCG

Green tea egcg extract exhibits a broad spectrum of bactericidal activity against various bacteria. Its bactericidal effects include damage to the bacterial cell membrane and inhibition of fatty acid synthesis and enzymatic activity [55]. H2O2, which is generated by EGCG, appears to play an indispensable role in the bactericidal actions of EGCG. The bactericidal action of EGCG was related to H2O2 level, as bactericidal action was inhibited by the increase of CAT concentration [14]. EGCG was found to have bactericidal activity at higher concentrations in the Salmonella assay, highly correlated with H2O2 production [56].

Green Tea EGCG Extract Application:

1. It is applied in healthy food.

2. It is applied in medical products.

3. It is applied in beverages and so on.
