Technical Field

The invention relates to the technical field of American ginseng extraction, and particularly relates to an American ginseng extraction process and an American ginseng extraction method.

Background

American ginseng has the double effects of nourishing yin and tonifying qi, calming the nerves and promoting intelligence, clearing heat and promoting fluid, and reducing pathogenic fire and relieving summer heat. The main component of American ginseng is ginsenoside, and the 5 types of saponin separated are respectively: ginsenoside R0, Rb1, Rg1, Re and pseudoginsenoside F11. New ginsenosides are isolated. The active ingredients of the American ginseng are basically the same as the types of the ginsenoside monomer, even the contained sapogenin is completely consistent, and the American ginseng is all oleanolic acid, panaxadiol and panaxatriol. However, because the content of Rb1 in panaxadiol monomer saponin of American ginseng is higher than that of ginseng, the difference in curative effect and application of the two is formed, and the two are characterized and cannot be replaced by each other. American ginseng saponin is one of the most main effective components in American ginseng and is also the most obvious substance of physiological activity. To date, a variety of saponin monomers have been extracted from American ginseng. Although the types of American ginseng saponin monomers are few, the American ginseng saponin monomers are mainly triterpenoids, have similar structures with ginsenoside, but some American ginseng saponin monomers are unique. American ginseng saponins can be divided into three major groups: the group Ra, the group Rb (including Ro, Ra1, Ra2, Ra3, Rb1, Rb2, Rb3, Rc, Rd and other subtypes) and the group Rg (including six subtypes Re, Rg1, Rg2, Rg3, Rh1 and Rh 2). Related studies have shown that several monomers in the Ra group are less physiologically active, while the Rb and Rg groups are relatively more physiologically active in these three broad groups. The study of the comparison of American ginseng and ginseng shows that the content of the American ginseng total saponin and the ginsenoside r64 in the American ginseng is obviously higher than that of the same dosage of ginseng, thereby explaining why the American ginseng is listed as a rare Chinese medicament. The traditional water extraction and alcohol precipitation method of the American ginseng has long process time, large energy and medicinal material loss and lower content of effective components in the extracted extract. In view of this, we propose an extraction process and method of American ginseng.

Disclosure of Invention

In order to make up for the above deficiencies, the invention provides an American ginseng extraction process and a method thereof.

The technical scheme of the invention is as follows: the method comprises the following steps:

step one, crushing American ginseng into coarse powder and sieving;

step two, placing the powder sieved in the step one into an extraction tank;

step three, adding 7-9 times of 60% ethanol solution;

step four, heating for the first extraction, and collecting stock solution for later use;

step five, continuously heating for secondary extraction, and collecting stock solution for later use;

step six, combining the stock solutions obtained in the step four and the step five, and placing the combined stock solutions in a vacuum decompression device for ethanol recovery;

and step seven, filtering the stock solution obtained in the step six to obtain a finished product.

As a preferred technical scheme, the first step is to sieve through a 12-14-mesh sieve.

Preferably, the heating temperature in the fourth step and the fifth step is 59-61 ℃.

As a preferable technical scheme, in the sixth step, the temperature of the vacuum pressure reducing device is 69-71 ℃, and the vacuum degree is 0.02-0.04 MPa.

As a preferable technical scheme, the seven-step filtration uses 200-mesh and 300-mesh filter cloth for filtration.

Compared with the prior art, the invention has the beneficial effects that:

the American ginseng is crushed and then added with 60 percent ethanol solution which is 7 to 9 times of the crushed American ginseng to be circularly extracted in an extraction tank, and then the American ginseng is placed in a vacuum pressure reduction device to be subjected to ethanol recovery, and stock solution is filtered to obtain a finished product.
