The invention provides a method for extracting fresh
ginseng with superhigh pressure equipment. The method specially comprises the following steps of selecting good-quality fresh
ginseng which is 4-5years old and has complete exteriority, adding water which is 0.5-1 time of the fresh
ginseng, placing the ginseng and the water in a
plastic bag, performing sealing, putting the
plastic bag in a superhigh pressure cabin at the pressure of 400 MPa, performing extraction for 5 minutes, taking an extracting solution, and performing filtering to obtain a fresh ginseng extracting solution. In the extraction process, sample materials do not need to be crushed, the prototype of the entire fresh ginseng can be maintained, and the exteriority is intact, so that the nature of the ginseng exteriority asa natural
filtration membrane can be used, substances with relative micromolecules can pass the exteriority, part of
macromolecular compounds can be prevented from passing the exteriority, and a fresh ginseng
stock solution is guaranteed to be clear and transparent. The fresh ginseng extracting solution can be used for preparing fresh ginseng oral liquid or beverages, and the made fresh ginseng oral liquid or beverages can obviously reduce the
fasting blood sugar of mice suffering from diabetes, can obviously improve the oral
sugar tolerance of the mice suffering from
type II diabetes, and besides, cannot raise the level of
serum insulin. The fresh ginseng extracting solution can be made into drugs, foods or health-care products for
