Active medicinal component extraction method

The invention discloses an active medicinal component extraction method, relates to the field of armadillidiam vulgare active component extraction, adopts a supercritical fluid extraction technology, and relates to a technology for separating a target compound from a solid or liquid by using a supercritical fluid as a solvent. The CO2 is used as the extraction agent, and is widely applied to the extraction and separation processes of medicines, foods and chemical products due to the unique physicochemical properties of the CO2 in a supercritical state and the ultrasonic wall-breaking assistance. The invention discloses a method for extracting active ingredients from tidal worms and belongs to the field of natural product chemistry. The active ingredients can be used for development of medicines, health care products or other biotechnology products. The preservation condition of the extract is 1-4 DEG C, the temperature is low, the extract can be preserved for a long time, and the stabilization and long-term p
