本发明是以哺乳动物的新鲜脏器(肝脏和脾脏)制务肝-脾抽出物。取屠宰的哺乳动物肝6—10份和脾0.5～2份混匀。混匀后的物质在一定温度下,在酵素存在下,在不存在氧的水媒质中(?)其反应,所得水相减压浓缩,浓缩物和乙醇混合。从水相中分离除去固体残渣,水相再减压浓缩,用乙醚处理浓缩物,再分离回收 The present invention is a liver-spleen extract prepared from fresh mammalian organs (liver and spleen). 6-10 livers of slaughtered mammals and 0.5-2 spleen were mixed. The mixed material is reacted in the absence of oxygen in a water medium (?) at a certain temperature in the presence of enzymes, and the resulting aqueous phase is concentrated under reduced pressure, and the concentrate and ethanol are mixed. The solid residue is separated and removed from the aqueous phase, the aqueous phase is concentrated under reduced pressure, the concentrate is treated with diethyl ether, and separated and recovered.
