| titleOfInvention | Method for extracting total flavones from radix puerariae employing enzyme preparation |
| abstract | The invention relates to a method for extracting total flavones from radix puerariae employing an enzyme preparation. The enzyme preparation adopted by the method is prepared from cellulase, xylanase, protease and amylase. The method comprises the following steps: crushing and sieving dry radix puerariae, and dissolving with distilled water; adding an enzyme preparation, reacting for a period of time, and centrifuging; adding the distilled water, repeatedly leaching, and carrying out vacuum concentration to obtain a puerariae total flavones extract; and adsorbing and eluting the obtained puerariae flavone extract through HPD-600 macroporous resin, concentrating and drying to obtain the puerariae total flavones with the purity of over 95% finally. The method provided by the invention is mild in reaction conditions; the conformation of a natural product can be kept; the stereochemical structure and the biological activity are not destroyed; keeping of the original medicine effect of effective components is facilitated; impurities in a system can be removed; the clarity of an extract liquid is improved; the extraction rate of the effective component of the radix puerariae is improved; the reaction conditions are optimized and combined; and the maximization of the extraction yield is realized. |
