Embodiment 1

[0024] The present embodiment provides a preparation method of saddle vine polyphenols, comprising the following steps:

[0025] S1: Pulverize the saddle rattan, and then pass through a 60-mesh sieve to collect fine powder with a particle size of less than 0.250mm;

[0026] S2: Using ethanol as the extraction solution, extract the fine powder in a 60°C water bath for 60 minutes, and then filter; repeat the extraction once, and combine the filtrate obtained from the two extractions; the quality of ethanol used in the two extractions is the same as that of the fine powder 10 times;

[0027] S3: concentrating the filtrate under reduced pressure until the ethanol is completely volatilized to obtain crude polyphenols;

[0028] S4: Dissolve the crude polyphenol in 5 times the volume of 70% ethanol aqueous solution, then load the sample on the AB-8 type macroporous resin column, and then elute with 2.0BV of 50% ethanol aqueous solution , the elution rate is 2.0BV·h -1 , to collect...

Embodiment 2

[0032] The present embodiment provides a preparation method of saddle vine polyphenols, comprising the following steps:

[0033] S1: Pulverize the saddle rattan, and then pass through a 60-mesh sieve to collect fine powder with a particle size of less than 0.250mm;

[0034] S2: Using ethanol as the extraction solution, extract the fine powder in a 70°C water bath for 90 minutes, and then filter; repeat the extraction once, and combine the filtrates obtained from the two extractions; wherein, the quality of ethanol used in the two extractions is the quality of the fine powder 20 times;

[0035] S3: concentrating the filtrate under reduced pressure until the ethanol is completely volatilized to obtain crude polyphenols;

[0036] S4: Dissolve the crude polyphenol in 5 times the volume of 70% ethanol water solution, then load the sample on the AB-8 macroporous resin column, and then elute with 2.0BV of 60% ethanol water solution , the elution rate is 2.0BV·h -1 , to collect the...

Embodiment 3

[0040] The present embodiment provides a preparation method of saddle vine polyphenols, comprising the following steps:

[0041] S1: Pulverize the saddle rattan, and then pass through a 60-mesh sieve to collect fine powder with a particle size of less than 0.250mm;

[0042] S2: Using ethanol as the extraction solution, extract the fine powder in a water bath at 80°C for 120 minutes, and then filter; repeat the extraction once, and combine the filtrate obtained from the two extractions; the quality of ethanol used in the two extractions is the same as that of the fine powder 30 times;

[0043] S3: concentrating the filtrate under reduced pressure until the ethanol is completely volatilized to obtain crude polyphenols;

[0044] S4: Dissolve the crude polyphenol in 5 times the volume of 70% ethanol water solution, then load the sample on the AB-8 macroporous resin column, and then elute with 3.0BV of 80% ethanol water solution , the elution rate is 2.0BV·h -1 , to collect the ...

Abstract

The present invention relates to a vine polyphenol and its preparation method and application. The preparation method comprises the following steps: pulverizing the vine polyphenol, and then sieving to collect the fine powder; extracting the fine powder with ethanol, and then filtering to collect the filtrate; The filtrate is concentrated until the ethanol is completely volatilized to obtain crude polyphenols; the crude polyphenols are dissolved in an aqueous ethanol solution with a volume fraction of 70%, and then loaded on an AB-8 macroporous resin column, and then the volume fraction is 50%- 80% ethanol aqueous solution was used for elution, and the eluate was collected; the eluate was concentrated to dryness under reduced pressure to obtain the polyphenols of Echinaceae. The present invention adopts the method of alcohol extraction to extract the vine polyphenols, and the prepared vine polyphenols have the advantages of high stability and good therapeutic effect on eczema caused by microbial infection, and can be applied to the preparation of prevention and / or treatment of eczema, especially microbial infection Caused by eczema medications.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to a saddle polyphenol and its preparation method and application. Background technique [0002] Saddle vine is a perennial herbaceous plant of the Convolvulaceae Ipomoea genus, which grows on tropical and subtropical beaches and belongs to the companion plant of mangroves. It often grows in patches on barren gravel beaches and other salt-tolerant plants to form coastal beach vegetation landscapes. In my country, it is widely distributed in Zhejiang, Taiwan, Fujian, Guangdong, Guangxi and other provinces. It can be used as medicine to treat inflammation, abdominal pain, poor urination, gonorrhea, etc. [0003] Saddle Vine is often used to treat a variety of ailments such as inflammation, abdominal pain, poor urination, gonorrhea, etc. "Fujian Folk Herbal Medicine" records that it has the effects of eliminating carbuncle and dissipating stagnation, expelling wind and dampn...
