| titleOfInvention | Method for extracting walnut ketones from epicarps of carya cathayensis Sarg and preparing walnut ketone standard product |
| abstract | The invention provides method for extracting walnut ketones from epicarps of carya cathayensis Sarg and preparing walnut ketone standard product. The method comprises the steps of: firstly, crushing the epicarps of the carya cathayensis Sargs, moistening with aqueous ammonia, adding 95 percent of ethanol solution, carrying out hot reflux extraction, extracting extract with chloroform to obtain carya cathayensis Sarg ketone sample liquid, concentrating the sample liquid, purifying by thin layer chromatography to obtain rough walnut ketone, further purifying the rough walnut ketone by using C18 reverse-phase column chromatography, collecting the rough walnut ketone eluent by segments, combining the eluent with purity larger than 95 percent detected by HPLC (High Performance Liquid Chromatography), and carrying out nitrogen blowing to remove a solvent, thus obtaining the walnut ketone standard product. For the method, the extraction process is simple, the walnut ketone has high yield and high purity, theoretical and practical application basis can be provided for comprehensively utilizing carya cathayensis Sarg resources by taking the epicarps of the carya cathayensis Sargs as raw materials, thus having an effect on changing wastes into treasures. |
