AI Technical Summary

Technical Problem

Existing flavonoid extraction methods are not suitable for extracting large quantities of biologically effective flavonoids from inexpensive raw materials with low flavonoid content, resulting in low extraction efficiency, high purification costs, and long cycles, making it difficult to achieve industrial production.

Method used

Flavonoids were extracted from the lees of light-aroma baijiu using microwave-assisted ethanol extraction combined with AB-8 macroporous resin separation and purification technology. Microwave-assisted extraction rapidly disrupted the plant cell walls, followed by extraction with medium and low concentration ethanol and centrifugation to remove impurities. Subsequently, gradient elution and concentration drying were performed using AB-8 macroporous resin to achieve efficient purification.

Benefits of technology

It achieves efficient extraction of high-purity flavonoids from inexpensive raw materials, shortens extraction time, reduces energy consumption, and improves extraction rate. It has good antioxidant and potential hypoglycemic effects and is suitable for the preparation of health food products.
