Abstract

The invention discloses a quality control method of lichee polyphenols and products thereof, and aims to provide the lichee polyphenols with extensive use and a method capable of simultaneously qualitative and quantitative determination of the content of various effective components in the litchi polyphenols and preparations thereof and building of comprehensive evaluation and monitoring of the quality. The method comprises the steps: with lichee peel, kernels and epicormic branches with leaves as raw materials, extracting to obtain polyphenols, further carrying out column chromatography and extraction, combining with HPLC semipreparative chromatography, and separating to obtain a compound 1 (-)-epicatechin, a compound 2 procyanidin A2, a compound 3 procyanidin B2, a compound 4 epicatechin-(4beta->8,2beta->O->7)-epicatechin-(4beta->8)-epicatechin called PC-C for short, a compound 5 B-type procyanidin dimer, and a compound 6 A-type procyanidin trimer. The quality control method belongs to the technical field of chemical detection.

Description

technical field

[0001] The invention discloses a quality control method of polyphenols and its products, in particular, a quality control method of litchi polyphenols and its products; it belongs to the technical field of chemical detection. Background technique

[0002] Plant polyphenols are the general term for polyhydric phenolic compounds, which are widely found in vegetables, fruits, beans, tea and other plants. The unique structure of polyphenols endows it with some unique chemical properties, making it anti-oxidant, preventing heart and brain Vascular disease, anti-tumor, anti-aging and other functions are more and more widely used in the fields of medicine, health food, cosmetics and functional beverages. Plant polyphenol antioxidant extracts that have been successfully developed and utilized include grape seed extract and green tea extract. The research results show that the total phenolic content and antioxidant activity of litchi extract are very close to those o...
