What is Epigallocatechin Gallate Solubility?

Epigallocatechin Gallate Solubility is one of the most effective active component in catechins, making up about 8% to 13% of the gross weight of environment-friendly tea, as well as is likewise the part with the highest content in catechins. (-)-Epigallocatechin gallate is an ester developed by α-diphenoxybenzopyran and also gallic acid. It has the basic residential property of phenolic anti-oxidant. There are 6 ortho phenolic hydroxyl teams in its molecular structure, so it has numerous properties superior to other catechins.

Epigallocatechin Gallate Solubility Uses

Epigallocatechin Gallate Solubility (EGCG) is a component extracted from Chinese environment-friendly tea. It is the primary active as well as water-soluble component of environmentally friendly tea. It is the get rid of the highest possible material of catechins, making up 9%-13% of the gross weight of environment-friendly tea, because With an unique stereochemical framework, EGCG has extremely strong antioxidant task. The antioxidant activity is at the very least 100 times that of vitamin C along with 25 times that of vitamin E.It can shield cells and also DNA from damage. This damages is believed to be associated with cancer cells, Heart problem as well as various other significant diseases belong, and also these results of EGCG are attributed to their capacity to scavenge oxygen totally free radicals (antioxidant).

Epigallocatechin Gallate Solubility plays an essential duty in the battle against cancer cells as well as cardiovascular diseases. Additionally, it is likewise made use of as a turnaround representative of growth multidrug resistance, which can boost the level of sensitivity of cancer cells to chemotherapy and minimize the toxicity to the heart.

Epigallocatechin Gallate Solubility is the main component of environment-friendly tea polyphenols, as well as likewise the major part of green tea catechins. The catechins consist of EGCG, EGC, ECG, EC, GCG, and so on, amongst which the antioxidant task is EC. Lots of studies have actually shown that EGCG It has anti-free extreme DNA damages, anti-radiation and also ultraviolet rays, stops oil peroxidation, decreases the web content of low-density cholesterol, ultra-low-density cholesterol as well as triglyceride in lotion, interferes with the signal transmission required for cancer cell survival, and also prevents carcinogenicity in diet Materials, together with various other enzymes and anti-oxidants in the intestines, liver, as well as lungs, obstruct the task of particular carcinogens, scavenge cost-free radicals, resist the effects of air pollution, sunlight direct exposure, and cigarette smoking, and also prevent skin aging and also wrinkling.

Epigallocatechin Gallate Solubility Biological Activity

Green tea and its extracts have strong weight-loss and fat-reducing effects. As early as 1999, it was found that green tea extract intervention can significantly improve the energy consumption and fat oxidation levels of young men. Some experiments based on cell level and animal models have also revealed the role of green tea and catechins in weight loss and fat loss. For example, studies have shown that Epigallocatechin Gallate Solubility can reduce the viability of 3T3-L1 preadipocytes and inhibit the differentiation ability of preadipocytes by inducing the production of ROS and activating the AMPK pathway, thereby reducing adipogenesis and controlling the expansion of adipose tissue. By intervening food-derived EGCG in male DIO mice, it was shown that EGCG can increase the level of fat oxidation, and EGCG reduced the visceral fat weight of rats in a dose-dependent manner. Studies have shown that in rats fed a high-fat diet supplemented with food-derived EGCG (3.2g/kgfood), after 16 weeks of feeding, the rats lost weight, decreased epididymal fat coefficient, and significantly decreased FFAs and fasting insulin levels. Based on previous research, the weight loss and fat loss mechanism of Epigallocatechin Gallate Solubility can be divided into direct mechanism and indirect mechanism. The direct mechanism is the effect of EGCG on the digestive organs, such as inhibiting the digestion and absorption of nutrients by inhibiting the activity of digestive enzymes and changing the intestinal flora. The indirect mechanism is that EGCG regulates the expression of obesity-related genes and proteins in AT, muscle tissue, and liver tissue.

Preparation of Epigallocatechin Gallate Solubility

1) Extraction and separation of tea polyphenols

Dry 10g of tea leaves in an oven and grind them into powder. After plugging the outlet of the funnel with absorbent cotton, put the tea leaves into a constant-pressure dropping funnel, and fill it with absolute ethanol. Use a circulating condensing device and heat with a water bath at a temperature of about 87°C. When the condensate drops out, start timing, and after 2 hours, replace the distillation device to concentrate the extract. Add activated carbon powder to the extract to decolorize, filter with suction and collect the filtrate, adjust the pH of the filtrate with 10% citric acid solution, then add a certain proportion of ethyl acetate and water for extraction, take the upper oily ester layer and Use a rotary evaporator to recover ethyl acetate and dry it to obtain crude tea polyphenols.

2) Pretreatment of polyamide

The polyamide was stirred in ethanol and soaked for 24 hours. After filtration, the filter cake was washed 3 times with 20 mL of ethanol each time (the ethanol can be recovered and reused). Pour the treated polyamide into the chromatographic column to allow the polyamide to settle naturally, release the excess ethanol solution in the column, make the liquid level slightly higher than the surface of the polyamide particles, close the piston, and then use 5% NaOH solution to , 10% acetic acid solution, and finally rinsed with distilled water until the pH of the effluent was 7.

3) Separation and collection of (-)-epigallocatechin gallate

Add appropriate amount of distilled water to dissolve the obtained tea polyphenol crude product and put it on a polyamide column. First use 100mL distilled water for elution, control the flow rate to 4mL/min, when the liquid level in the chromatography column is slightly higher than the height of the polyamide column, use a certain concentration of ethanol-water solution for elution, the flow rate is 3.0mL/min, to Complete elution. Fractions containing (-)-epigallocatechin gallate were combined, ethanol was recovered, evaporated and dried at a temperature of 40° C., and solid powder of (-)-epigallocatechin gallate was recovered.
