based on carbon dioxide-induced switchable hydrophilic solvent as an extractant, and synergistic ultrasound-assisted extraction and separation of xanthogin polysaccharides.
The research method is not only efficient, recyclable, and meets the requirements of green production, but also provides a new strategy
for extracting plant polysaccharides and other active ingredients.
The research results were published in
Food Chemistry.
Huang Jin is a homologous plant of medicine and food, polysaccharides as its main functional active ingredients, with immune regulation, antioxidant, regulation of blood sugar and other effects, has been widely used in food, medicine and other fields
.
At present, there are two commonly used xanthosin polysaccharide extraction methods, one is water extraction, but the extraction efficiency is low, and the other is alkali extraction, which is easy to destroy the structure of polysaccharides and bring environmental pollution and other problems, which is not in line with the concept of
green production.
It is imperative to find a green and environmentally friendly extractant to extract yellow extract polysaccharides
.
In recent years, switchable hydrophilic solvents have been introduced as an environmentally friendly green solvent that can be reversed by changing triggers such as temperature, pH and carbon dioxide and have been used in the separation and recycling
of medical waste, petroleum and packaging materials.

of medical waste, petroleum and packaging materials.
In this study, researchers discovered a new method for extracting and separating xanthogin polysaccharides with carbon dioxide response as an extractant, and prepared a series of recoverable switchable hydrophilic solvents with carbon dioxide response by constructing different amines and water, and used ultrasound to assist in extracting xanthogin polysaccharides
.
When carbon dioxide is introduced, the amine in the solution is protonated, the solution becomes hydrophilic, and the solvent extracts the yellow essence polysaccharides; When nitrogen is introduced, the solution becomes hydrophobic and the extractant is separated and recovered
.
The results show that switchable hydrophilic solvents have good
reusability.
Under the best experimental conditions, the extraction rate of polysaccharide extracted by this method is much higher than that of traditional hot water extraction method, and it has broad application prospects
in the green separation of active ingredients of natural products.
