Quinoa flavone extraction and purification process

Abstract

The invention discloses a quinoa flavone extraction and purification process. The process comprises the following steps of: (1) raw material pretreatment; (2) solvent extraction; and (3) purification.The invention belongs to the technical field of flavone extraction and purification, and particularly provides the quinoa flavone extraction and purification process. Through pretreatment of solventextraction, most lipid substances are removed; ultrasonic cavitation is added in reflux extraction, so that liquid generates a resonance phenomenon to cause cell wall rupture, the solvent penetrationis increased, and flavone components are dissolved out at a high speed, so that the extraction rate is increased; 15% sodium chloride is added into a crude extract, so that soluble proteins can be separated out; and purification is carried out through silica gel, so that the process is safe, high in extraction rate, non-toxic, pollution-free and better in separation effect.

Description

technical field

[0001] The invention belongs to the technical field of flavonoid extraction, and specifically refers to a process for extracting and purifying quinoa flavonoids. Background technique

[0002] Quinoa, also known as South American quinoa, quinoa, etc., is a herbaceous crop of Chenopodiaceae. Quinoa is native to the Andes region of South America and has been cultivated for more than 5,000 years. Quinoa is rich in functional nutrients. It is recognized by the Food and Agriculture Organization of the United Nations (FAO) as the only food that can meet the basic nutritional needs of the human body with a single plant. It is recommended as the most suitable complete nutritional food for human beings. It is known as super grain and nutritional gold. Studies have shown that the flavonoids contained in quinoa have many functions such as scavenging free radicals, anti-oxidation, anti-aging, anti-tumor, anti-virus, lowering blood pressure, lowering blood lipids, and en...
