Problems solved by technology

[0004] At present, most of the researches on the effective parts of Grass coral focus on flavonoids, coumarins and organic acid compounds, and there are very few studies on phenolic compounds. The patent with publication number CN 1879672A discloses a caffeic acid 3,4- The total polyphenols in the effective part of Sargassum with dihydroxyphenethyl ester as the active ingredient and the patent with the publication number of CN 101020637A disclose a method for preparing total polyphenols containing rosmarinic acid using Sargassum as a raw material, but the former The above-mentioned active ingredient caffeic acid 3,4-dihydroxyphenethyl ester has not been reported in the literature that it has been isolated from Grass coral, and the latter has no clear other phenolic components in the total polyphenols except rosmarinic acid, and The key lies in the fact that the preparation method of the effective parts adopted by the two is relatively cumbersome and difficult to implement, which is not convenient for industrialized mass production.

Embodiment 1

[0060] Grass coral crude powder 5kg, add 10 times the amount of water, decoct 2 times, 2 hours each time, combine the decoction liquid, high-speed centrifugation of the decoction liquid, ultrafiltration of the centrifugation liquid with a polysulfone membrane with a molecular weight cut-off of 200,000, ultrafiltration Adjust the pH value of the filtrate to 1.0, put it on the HPD-100 macroporous adsorption resin column for adsorption, first elute with 2 to 3 times the column volume of water, then elute with 70% ethanol with a pH of 14.0, collect the ethanol eluate, Concentrate under reduced pressure and dry in vacuo to obtain 20.56 g of the effective part extract. In terms of rosmarinic acid, it contains 62.52% of total phenolic acids.

Embodiment 2

[0062] Grass coral crude powder 5kg, add 10 times the amount of water, decoct 2 times, 2 hours each time, combine the decoction liquid, high-speed centrifugation of the decoction liquid, ultrafiltration of the centrifugate with a cellulose acetate membrane with a molecular weight cut-off of 150,000, ultrafiltration Adjust the pH value of the filtrate to 2.0, put it on the HPD-400 macroporous adsorption resin column for adsorption, first elute with 2 to 3 times the column volume of water, then elute with 50% ethanol with a pH of 10.0, collect the ethanol eluate, Concentrate under reduced pressure and dry in vacuum to obtain the effective part extract. In terms of rosmarinic acid, it is 18.25g, which contains 59.11% of total phenolic acids.

Embodiment 3

[0064] Grass coral crude powder 5kg, add 10 times the amount of water, decoct 2 times, 2 hours each time, combine the decoction liquid, high-speed centrifugation of the decoction liquid, ultrafiltration of the centrifugate with a polytetrafluoroethylene membrane with a molecular weight cut-off of 20,000 , adjust the pH value of the ultrafiltrate to 4.0, put it on the HPD-500 macroporous adsorption resin column for adsorption, first elute with 2 to 3 times the column volume of water, then elute with 30% ethanol with a pH of 11.0, and collect the ethanol to elute solution, concentrated under reduced pressure, and dried in vacuum to obtain 16.85 g of the effective part extract. In terms of rosmarinic acid, it contains 58.12% of total phenolic acids.

Abstract

The invention relates to a phenolic acid effective part extracted from the traditional Chinese medicine-chloranthus glaber and preparation method thereof. Phenolic acid compound contained in the effective part includes rosmarinic acid, protocatechuic acid, isofraxidin and caffeic acid, and the total content of the phenolic acid compound in the extractive is no less than 50 percent. The chloranthus glaber is extracted by water or ethanol, extracting solution is processed by high-speed centrifugation, centrifugation solution is processed by ultrafiltration by an organic composite film, the pH value of ultrafiltrate is regulated to range from 1 to 7, and the ultrafiltrate is applied to a resin column to be absorbed; according to column volume, 2 to 3 times water is used for elution, and then 10 to 70 percent of ethanol with the pH value ranging from 8 to 14 is used for elution; and ethanol elution solution is collected, concentrated and dried, thereby obtaining the extractive of the effective part.

Description

technical field [0001] The invention relates to an extract of effective parts of traditional Chinese medicine, in particular to an effective part of phenolic acids extracted from Chinese herbal coral coral, its preparation method and its application in the preparation of antibacterial and anti-inflammatory drugs and auxiliary therapeutic drugs for cancer. Background technique [0002] Grass coral (Sarcandra glabra (Thunb.) Nakai) is a plant of Chrysanthemum orchidaceae, also known as Sarcandra glabra, Jiujiecha, elderberry, elderberry, etc. Medicinal whole herb has the functions of antibacterial and anti-inflammatory, heat-clearing and detoxifying, expelling wind and dampness, promoting blood circulation and relieving pain, dredging menstrual flow and setting bones, etc. In recent years, it has also been used as an adjuvant therapy for cancer, and has obvious curative effects on pancreatic cancer, gastric cancer, rectal cancer, liver cancer, and esophageal cancer.
