Problems solved by technology

[0002] It is only seen that in the 1950s, foreign scholars had carried out a small amount of research reports on the chemical components of Dendrobium rosea, from which five alkaloid components were isolated and identified (see the figure below Magnus Elander et al, Studies on Orichidaceae Alkaloids, Acta Chenical Scandinavica 27(1973):1907-1913), there is no report on the activity of medicinal materials and their monomer substances

Embodiment 1

[0016] The crushed and dried Dendrobium rose medicinal material was extracted 3 times with 10 times the amount of ethanol-water mixed solvent (90:10), the extraction time was 3, 3, and 2 hours respectively, filtered, the filtrate was concentrated to dryness, and soaked with 5% hydrochloric acid-water solution, Adjust the pH to weak acidity (pH=4~5), the aqueous solution is super-acid styrene-type cation exchange resin column (model: 001×7), remove impurities with 3 times the amount of 60% ethanol water mixed solvent, and then use 2 times the amount of Elute with ammonia water-ethanol solvent (1:8), adjust the pH value of the eluent to neutral with hydrochloric acid, and concentrate to obtain the total alkaloids of Dendrobium rosea. The content of total alkaloids in Dendrobium rosea was determined by acid dye colorimetry. The determination method is as follows, and the total alkaloid content is 80%.

Embodiment 2

[0024] Method b. The crushed Dendrobium officinale medicinal material was reflux extracted with 10 times the amount of 95% ethanol for 3 times, each extraction time was 3, 3, and 2 hours respectively, and then refluxed with 10 times the amount of 75% ethanol for 2 hours, and reduced pressure Recover the solvent to obtain a concentrated solution, extract once with an equal volume of petroleum ether (60-90°C), discard the organic layer, add 0.3 times the amount of 5% hydrochloric acid, stir and filter, collect the filtrate, and adjust the pH value of the filtrate to 9 with ammonia water ~10 (visible precipitation), extracted 3 times with equal volume of chloroform, and the chloroform extract was concentrated into a reddish-brown extract to obtain the total alkaloids of Dendrobium rosea, and the total alkaloid content was measured according to the method of Example 1, and the total alkaloids were prepared by this method The content is 86%.

Embodiment 3

[0026] Method c. The crushed Dendrobium rose medicinal material was soaked with 8 times the amount of 85% ethanol for 24 hours, percolated, the percolated solution was combined, the ethanol was recovered under reduced pressure and concentrated to obtain a concentrated water extract, which was extracted once with an equal volume of petroleum ether. After extraction, add 5% hydrochloric acid to the aqueous solution to pH 2-3, filter, add saturated sodium carbonate solution to the filtrate to pH 9-10, extract twice with equal volume of chloroform, wash the extract with water, and evaporate to dryness under reduced pressure. Total alkaloids from Dendrobium rosea. The total alkaloid content was measured according to the method in Example 1, and the total alkaloid content prepared by this method was 83%.

Abstract

The invention relates to an application of total dendrobium crepidatum alkaloids in preparing a medicament for treating acute and chronic inflammation, acute and chronic arthritis or rheumatoid arthritis diseases, and the content of the total dendrobium crepidatum alkaloids is 80-91 percent; and shown through a great amount of experiments by an inventor, the total dendrobium crepidatum alkaloids have a good effect on inflammation treatment. The total dendrobium crepidatum alkaloids have better stability and good anti-inflammation activity, and can be used for preparing medicaments for treating corresponding diseases. The total dendrobium crepidatum alkaloids have clear activity, and the experimental materials come from plants, so that the cost is low.

Description

technical field [0001] The present invention relates to the extract of Dendrobium rosea, in particular to the application of total alkaloids of Dendrobium rosea in the preparation of medicines for treating acute and chronic inflammation, acute and chronic arthritis or rheumatoid arthritis. Background technique [0002] It is only seen that in the 1950s, foreign scholars had carried out a small amount of research reports on the chemical components of Dendrobium rosea, from which five alkaloid components were isolated and identified (see the figure below Magnus Elander et al, Studies on Orichidaceae Alkaloids, Acta Chenical Scandinavica 27(1973): 1907-1913), there is no report on the activity of medicinal materials and their monomeric substances. [0003] Contents of the invention [0004] The object of the present invention is: a kind of total organism of the Chinese medicinal material Dendrobium roseum which has the medicinal use for treating acute and chronic inflammat...
