Abstract
The invention relates to a method for extracting tea polyphenol and chlorophyll from green tea and application of a compound of the tea polyphenol and the chlorophyll to cosmetics. The method comprises the following steps: carrying out ultrasonic washing, fixation and crushing treatment on fresh green tea leaves; adopting an ultrasonic extraction method and adding 85 percent ethanol into an extraction solution; filtering with an ultra-filtration membrane; concentrating filtrate to obtain high-purity tea polyphenol and chlorophyll products. According to the method provided by the invention, extremely great impact wave and shearing force are generated through mechanical crushing and cavitation effects of ultrasonic waves, and formation, enlarging and closing of liquid holes, so that cells are crushed to release substances in the cells. The method has the advantages of short time, low temprature, high extraction rate and the like. The concentration, extraction rate and extraction speed ofthe method are better than those of a traditional extraction method. Under the technological condition that the tea polyphenol and the chlorophyll are extracted through the ultrasonic wave, the yieldof the product is improved by about 30 percent when being compared with that of a conventional solvent extraction method; the extracted compound of the tea polyphenol and the chlorophyll is used in the cosmetics and has an anti-oxidization and anti-pollution protection effect on skin, so that the skin-care and beautifying effect is realized.
Description
[technical field] [0001] The invention relates to the technical field of biological extraction, in particular to a method for extracting tea polyphenols and chlorophyll from green tea and its application in cosmetics. [Background technique] [0002] Green tea is one of the main teas in China. Green tea is made without fermentation and retains the natural substances of fresh leaves. It contains tea polyphenols, catechins, chlorophyll, caffeine, amino acids, and vitamins. There are also many other nutrients. These natural nutrients in green tea have special effects on anti-aging, anti-cancer, anti-cancer, sterilization, and anti-inflammatory. Therefore, green tea has always been the top grade for health and beauty. [0003] ·Green tea anti-aging [0004] Helps to delay aging. Tea polyphenols have strong antioxidant and physiological activities, and are scavengers of free radicals in the human body. Studies have shown that 1 mg of tea polyphenols can scavenge excessive free...
