Preparation method of canophyllic polyphenol and application thereof

Abstract

The invention discloses a preparation method of canophyllic polyphenol and an application thereof. The preparation method comprises the following steps that: 1) crab apple is used as raw material to be extracted to obtain the extraction liquid of crab apple; 2) nanometer filter membrane is used for separating the extraction liquid of the crab apple so as to remove the condensed tannin and the biological large molecular substance and to obtain the filtered extraction liquid of the crab apple; 3) the obtained extraction liquid of the crab apple is decompressed and concentrated, and the concentrated liquid is sprayed and dried to obtain the canophyllic polyphenol extraction finished product. The method further comprises the following steps between the step 2) and the step 3): the extraction liquid of the crab apple after being filtered and obtained in step 2) is absorbed by large-porous resin, then the extraction liquid is washed by water so as to remove the foreign matters, lower alcohol water solution is used for desorbing the extraction liquid so as to obtain the extraction liquid of the crab apple after the desorption. The water solubility of the crab apple extraction liquid is improved, and the content of the biological polyphenol is remarkably improved; and moreover, the canophyllic polyphenol can be used as an active additive for hydro-base products.

Description

technical field The invention relates to crabapple biological polyphenols and a preparation method thereof. Background technique The polyphenols of crabapple fruit are mainly composed of flavonoids such as catechin, epicatechin, proanthocyanidin, phlorizin, phloretin, and quercetin with biological activity. Oligomerization and high polyflavonoids of flavan-3 alcohol structure such as anthocyanins, as a powerful antioxidant that exists naturally, have the function of significantly removing free radicals in the human body. Medical research has proved that there are more than 70 diseases and diseases in humans. Related to free radicals, such as: cardiovascular, cancer, rheumatoid, premature aging, etc. Modern pharmacological research has found that polyphenols with flavan-3 alcohol structure can also significantly reduce low-density lipoprotein. Quercetin is the main active substance in crabapple fruit. Pharmacological studies have shown that it has anti-tumor, anti-oxidation,...

Problems solved by technology

However, the polyphenols obtained in the prior art have poor water solubility and low polyphenol content, so they cannot be used as additives for water-based products such as functional drinks and cosmetics.
