A compound
valerian extract for tranquilizing and allaying excitement is made from 1-5 parts by weight of
valerian extract and 1-5 parts by weight of magnolia
vine fruit extract by a combined extraction method and a separated extraction method; the combined extraction method is as follows: coarse
powder of various bulk drugs are mixed proportionally, the mixture is percolated or refluxed with an extraction
solvent to obtain extracting solution, the extracting solution is depressurized to recover the extracting
solvent until no smell of
ethanol exists, the solution is filtered to obtain filtrate which is diluted and eluted on a
macroporus adsorbent resin column with 60-90% of
ethanol which is six times of the volume of the column, and the eluent is dried to obtain the extract; the separated extraction method is as follows: coarse
powder of various bulk drugs, namely, the valerian and magnolia
vine fruit are respectively percolated or refluxed with the extracting
solvent to obtain various extracting solutions, the extracting solutions are respectively depressurized to recover the extracting solvent until no smell of
ethanol exists, the solution is filtered to obtain the filtrate which is diluted and eluted on a
macroporus adsorbent resin column with 60-90% ethanol which is six times of the volume of the column, the eluent is dried to obtain the extract, and the compound
valerian extract is obtained by mixing the obtained valerian extract and magnolia
vine fruit extract; and the extracting solution is 45-95% ethanol water solution. The compound valerian extract can be used for preparing medicines or foods for tranquilizing and allaying excitement, preventing and treating
