AI Technical Summary
Existing polyphenol extraction technologies from Cyclocarya paliurus leaves suffer from problems such as unsatisfactory extraction efficiency, long extraction time, large solvent consumption or residual risks, high energy consumption, expensive equipment, easy damage to the structure of active ingredients, and difficulty in achieving both high yield and high purity.
A multi-step method was adopted, which involved fermentation to disrupt the cell wall, extraction with ethanol and sodium tripolyphosphate aqueous solution, membrane separation, and purification with D201 macroporous anion exchange resin. The method combined fermentation and drying under specific conditions, utilized sodium tripolyphosphate to improve the water solubility and antioxidant properties of polyphenols, removed impurities through membrane separation, used D201 macroporous anion exchange resin for adsorption and separation, and finally achieved efficient purification by ethanol elution.
It achieves efficient, rapid, and environmentally friendly polyphenol extraction, reduces energy and solvent consumption, improves the purity and yield of polyphenols, avoids structural damage, and is suitable for large-scale industrial production and long-term storage.
