METHOD FOR PREPARING RADIX CODONOPSIS EXTRACT FROM RADIX CODONOPSIS LEFTOVER MATERIAL

摘要

A method for preparing a radix codonopsis extract from a radix codonopsis leftover material, comprising: first adding water, cellulose, and β-glucosidase in the radix codonopsis leftover material; uniformly mixing and carrying out enzymatic hydrolysis; and then extracting with a solvent, filtering, concentrating, and drying to obtain the radix codonopsis extract. The amount of β-glucosidase added is 1-1.5 times that of the cellulose. The method has the advantages of saving resources, low cost, and high active ingredient content of the extract, etc.
