Abstract

The invention relates to an extracting method of effective components from cordyceps mycelia and in particular relates to a tank group type countercurrent cordyceps extracting method, which comprises the following steps: putting the cordyceps mycelia and alcohol in a tank group type countercurrent extracting device, wherein the concentration of the alcohol is 90-98% and the mass of the alcohol is 8-12 times that of the cordyceps mycelia; performing at least first circulation extraction, second circulation extraction and third circulation extraction, wherein each tank group includes three extracting tank which are jointly used and in serial connection, the countercurrent extracting flow speed is 25-35 min per tank and the extracting temperature is 30-80 DEG C; collecting to obtain primary extracting liquid; pre-treating to obtain pre-treated liquid; filtering out deposition and taking supernatant; reducing pressure and performing vacuum concentration on the supernatant to 1.25-1.35 specific gravity to obtain concentration liquid; finally performing spray drying on the concentration liquid to obtain power product. According to the extracting method, free sterols, cordycepin, adenosine and polysaccharide are effectively extracted from the cordyceps mycelia and on the premise that the extracting rate is not lowered, the usage amount of an extracting solvent can be reduce by above 2 / 3.

Description

technical field [0001] The invention relates to a method for extracting active ingredients from cordyceps mycelium, in particular to a method for extracting cordyceps in a tank group countercurrent manner. Background technique [0002] The tank group dynamic countercurrent extraction process is to connect more than two dynamic extraction tank units in series, and the extraction solvent is transported through each tank sequentially from low to high along the solute concentration gradient of each tank in the tank group. The medicinal material is kept for a certain extraction time and applied repeatedly. This technology mainly utilizes the concentration gradient difference of the active ingredients in the solid-liquid (medicinal material and solvent) phase, and gradually diffuses the active ingredients in the medicinal material into the extraction solvent with a lower initial concentration, so as to achieve the maximum transfer of the active ingredients in the medicinal materia...
