PURPOSE:To obtain a tasty refreshing beverage having ataractic and harmonizing actions by treating an extract solution from a leaf of Bupleurum falcatum L. under specific conditions and then efficiently extracting an essence of a specific molecular weight from the leaf of the Bupleurum falcatum L. CONSTITUTION:This method for producing a herb beverage is to alkalinize an extract solution of a leaf of Bupleurum falcatum L. with KOH, NaOH, Ca(OH)2, etc., continuously extract the extract solution with ethyl acetate, carry out the extraction until the ethyl acetate becomes colorless, then acidify the alkaline extract solution from the leaf of the Bupleurum falcatum L. with HCl, H2SO4, H2C2O4, etc., continuously reextract the acidified extract solution with ethyl acetate, perform the extraction until the ethyl acetate layer becomes colorless, neutralize the extract solution from the leaf of the Bupleurum falcatum L. with KOH, NaOH, Ca(OH)2, CaCO3, etc., filter the neutralized extract solution, remove salt components by an ion exchange resin treating, a dialytic membrane methods, etc., corresponding to the method for neutralization, then concentrate and separate the solution according to a reverse osmosis membrane concentration method (1000 fractionation molecular weight under 10kg/cm<2> pressure) and perform the extraction of the essence from the leaf of the Bupleurum falcatum L. containing an ingredient having >=1000 molecular weight. Furthermore, the resultant essence is preferably used as a raw material for a refreshing beverage or a healthy food. |
