Embodiment 1

[0014] Add 2.5kg of Trichophyllum powder after passing through an 80 mesh sieve, add 20L of 50% ethanol, cold soak overnight, filter and recover under reduced pressure to obtain a paste sample, add n-hexane for repeated extraction, recover the extract under reduced pressure, and set the volume to 1L. Add 1% NaOH solution to dissolve the phenolic substances. After fully dissolving, add 1% HCL solution after separating the water layer through the separating funnel to reduce the phenolic substances, then use ethyl acetate to extract the aqueous layer to separate the phenolic substances, combine the extraction layers, and reduce After pressure recovery, wash pure solution to wash pure. The purity of GC-MS is 65.824%.

Embodiment 2

[0016] Add 2.5kg of Trichophyllum powder passed through an 80-mesh sieve to 20L of 70% ethanol, cold-soak overnight, filter and recover under reduced pressure to obtain a paste sample, add n-hexane for repeated extraction, recover the extract under reduced pressure, and set the volume to 1L. Add 2% NaOH solution to dissolve the phenolic substances. After fully dissolving, add 2% HCL solution to reduce the phenolic substances after the water layer is separated by a separatory funnel, then use ethyl acetate to extract the aqueous layer to separate the phenolic substances, and repeat the above-mentioned alkali extraction. In the sinking step, the extraction layers were combined, and after recovery under reduced pressure, they were washed with the pure solution, and the GC-MS detection purity reached 83.373%.

Embodiment 3

[0018] Add 2.5kg of Trichophyllum powder after passing through an 80-mesh sieve, add 20L of 80% ethanol, cold-soak overnight, filter and recover under reduced pressure to obtain a paste sample, add n-hexane for repeated extraction, extract under reduced pressure and recover, and set the volume to 1L. Add 3% NaOH solution to dissolve the phenolic substances. After fully dissolving, add 3% HCL solution to reduce the phenolic substances after separating the water layer through the separatory funnel, then use ethyl acetate to extract the aqueous layer to separate the phenolic substances, and repeat the above-mentioned alkali extraction. Sink twice, combine the extraction layers, recover under reduced pressure, wash with the pure solution, and the GC-MS detection purity reaches 92.051%, the results are shown in figure 2 .

Abstract

The invention discloses a method for extracting aspidinol from blocks. Dryopteris fragrans (L.)Schott is taken as an original material, and a method for quickly extracting and separating the aspidinol is found; the extracting time can be shortened to 4-10 hours; and a foundation is laid for wide application of the Dryopteris fragrans (L.)Schott.

Description

technical field [0001] The invention relates to a method for rapidly extracting cenomol, in particular to a method for rapidly separating and extracting cenomol by taking D. elegans as a raw material. Background technique [0002] Trichomonad has strong antibacterial activity, and its main antibacterial active substance is phloroglucinol substance cequol, but there is no method for rapid extraction and separation of cenomolicol, which limits the Wide application of hair fern. Contents of the invention [0003] The present invention provides a kind of method of fast extracting cephol, adding ethanol to the pulverized Trichophyllum powder, adding n-hexane to extract after filtering and concentrating, adding NaOH solution to the extract to dissolve phenolic substances, and Add HCL solution to the water layer to reduce the phenolic substances, then use ethyl acetate to extract the water layer to separate the phenolic substances, repeat the above steps of alkali extraction, ac...
