Problems solved by technology

Compared with water extraction, the organic solvent extraction method consumes less energy, has a higher extraction rate, and can effectively reduce the denaturation of polyphenols during the extraction process, but the residual organic solvent and the pressure on the environment have always restricted this method. widespread application of the law
[0005] At present, there are not many published data on the separation and purification of betel lang polyphenols, and there is no data suitable for industrial production

The betel lang polyphenol extract is extracted from betel langlag, the preparation method is simple, the extraction efficiency is high, the production cost is low, the safety is high, and it is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of polyphenol preparation, and specifically relates to a method for preparing polyphenol from betel dregs. Background technique [0002] Polyphenols refer to plant phenols with multiple phenolic hydroxyl groups in the molecule. There are very high levels of natural polyphenols in the fruit of betel dregs. Plant polyphenols have strong antioxidant capacity, which is 20 times that of vitamin C at the same dose, so they can effectively remove Oxygen free radicals, thereby reducing the damage of oxygen free radicals to normal cells, and playing a protective role. At the same time, polyphenolic compounds can also prevent the formation and accumulation of potential carcinogenic substances in the human body, improve metabolism, and have significant anti-cancer effects. In addition, some polyphenols with special structure in betel langma fruit have some special effects. [0003] The application of polyphenols in ...
