Problems solved by technology

[0004] In the above-mentioned patent, after the gentian is extracted with water, the precipitate is filtered and discarded. Since only part of the components in the gentian are water-soluble components, the water-insoluble components contained in the precipitate have not been extracted, resulting in the active ingredients of the gentian underutilized

Abstract

The invention discloses an extraction process of radix geutianae extract, which relates to the technical field of the extraction of natural products, and solves the problems that active ingredients ofradix geutianae are not sufficiently extracted and utilized. The extraction process comprises the following steps: step I, crushing air-dried radix geutianae to 50 to 100 meshes, and obtaining radixgeutianae powder; step II, adding the radix geutianae powder into a container, adding pure water into the container, stirring and extracting at normal temperature, filtering after the extraction, andobtaining a water extraction solution and filter residues; step III, extracting the filter residues in step II by using ethanol, filtering to remove precipitates, and obtaining an ethanol extraction solution; and step IV, uniformly mixing the water extraction solution and the ethanol extraction solution, vacuum concentrating, drying, and obtaining the radix geutianae extract. The extraction process in the invention is simple, the condition is moderate, the loss of active ingredients can be reduced, the active ingredients in the radix geutianae can be effectively extracted, the radix geutianaeis sufficiently extracted and utilized, the yield of the active ingredients is increased, and the content of the active ingredients in the radix geutianae extract is increased.

Description

technical field [0001] The invention relates to the technical field of natural product extraction, more specifically, it relates to a gentian extract and an extraction process thereof. Background technique [0002] Gentiana is the root and stem of the perennial herbaceous plant Gentiana gentiana of the family Gentianaceae. It is mainly produced in the Northeast region. It can be harvested in spring and autumn, and the quality of those harvested in autumn is the best. Roots and rhizomes are used as medicine. Bitter in the mouth, cold in nature, its function is to clear away heat and dampness. It has a very strong effect of purging liver and gallbladder excess fire, and can relieve wind, relieve spasm and relieve pain. [0003] The Chinese invention patent with the publication number CN106946999A discloses a decolorization method of gentian polysaccharides. The process flow is: gentian pulverization→sieving→petroleum ether degreasing→80°C water bath extraction→concentrating ...
