| titleOfInvention | Method for simultaneously preparing total saponins, total flavonoids and oil unsaponifiable matter of ginseng stem leaves |
| abstract | The invention provides a method for simultaneously preparing total saponins, total flavonoids and oil unsaponifiable matters of ginseng stems and leaves, belonging to the field of preparation methods of ginseng extracts. The method comprises processing dried stems and leaves of Ginseng radix into powder, adding petroleum ether, sodium hydroxide, n-hexane, ethyl acetate, acetonitrile and water, and extracting by magnetic stirring; standing after extraction, collecting the upper layer solution, and concentrating under reduced pressure or normal pressure to obtain unsaponifiable matter of ginseng stem and leaf oil; respectively taking the middle layer solution and the lower layer solution, concentrating, loading onto macroporous resin column, eluting with water until the water eluate is colorless, clear and transparent, eluting with ethanol solution until the ethanol eluate is colorless, clear and transparent, collecting the ethanol eluate, recovering ethanol, and drying to obtain dry extract-like total flavonoids of ginseng stem and leaf and total saponins of ginseng stem and leaf. The method is convenient, efficient, easy to operate and low in cost, improves the utilization rate of the ginseng stems and leaves, can meet the development and utilization in the fields of medicine, food and chemical industry, and has great application and development values. |
