Embodiment 1

[0044] 1) pre-treatment: breaking the rough perilla;

[0045] 2) Extraction: Mix the raw material and deionized water at a ratio of 1:4 and put it into the extraction tank, heat it to boiling and keep the temperature for 3 hours, collect the first extraction material liquid, and add 3 times the amount of deionization for the second extraction Water, heat and boil for 3 hours, collect the second extraction material liquid, add 2 times the amount of deionized water for the third extraction, heat and boil for 2 hours, collect the third extraction material liquid.

[0046] 3) Concentration under reduced pressure: the extraction material liquid is introduced into a concentrator for concentration under reduced pressure, the temperature is controlled below 80 degrees Celsius, and the degree of vacuum is controlled above 0.07 MPa.

[0047] 4) Centrifugation: the concentrated extract is centrifuged by a centrifuge.

[0048] 5) The concentrated and centrifuged extract directly enters t...

Embodiment 2

[0054] 1) Pre-treatment: crush the rough persimmons that have been sorted and removed from impurities.

[0055] 2) Extraction: Put the raw materials into a clean extraction tank, add 6 times the amount of 70% (V / V) ethanol, and extract for the first time under reflux for 3 hours, count the time from the boiling of the solvent, control the temperature at 80°C, and press out when the temperature is up. For the medicinal solution, add 6 times the amount of 70% (V / V) ethanol for reflux extraction for 3 hours for the second time, and combine the filtrates;

[0056]3) Ethanol recovery: pump the extracted feed liquid into a concentration tank for concentration under reduced pressure to recover ethanol, the temperature is controlled below 70°C, and the vacuum degree is controlled above 0.06MPa. After recovering until there is no alcohol smell, the medicine is hydraulically injected into the liquid storage tank;

[0057] 4) Stand still, cool, and centrifuge the cooled medicinal soluti...

Embodiment 3

[0064] 1) Pre-treatment: crush the rough persimmons that have been selected and removed from impurities.

[0065] 2) Extraction: Mix the raw materials with 70% ethanol by weight at a ratio of 1:6, and perform ultrasonic extraction. The extraction conditions are working frequency 60KHz, time 120min, and extraction 2 times;

[0066] 3) Ethanol recovery: the extracted feed liquid is introduced into a concentration tank for concentration under reduced pressure to recover ethanol, the temperature is controlled below 70°C, and the vacuum degree is controlled above 0.06MPa. After recovering until there is no alcohol smell, the material is hydraulically poured into the liquid storage tank;

[0067] 4) Stand still, cool, and centrifuge; centrifuge the cooled feed liquid with a centrifuge, and the feed liquid should be free of any sediment;

[0068] 5) Column adsorption: put the centrifuged feed liquid into the macroporous resin column, the type of resin column is AB-8.

[0069] 6) Wa...

Abstract

The invention provides a method for extracting shanzhiside methyl ester from phlomis umbrosa, and mainly solves the problems that extracted shanzhiside methyl ester in the prior art is low in content and yield and contains more impurities. The method for extracting the shanzhiside methyl ester from phlomis umbrosa comprises the following steps: 1) dissolving medium extraction; 2) concentration; 3) separation and purification; and 4) drying and extraction. The shanzhiside methyl ester produced by the method is high in content, the production process is simplified, the production cycle is shortened, and the phlomis umbrosa industrialized production is facilitated.

Description

technical field [0001] The invention relates to a method for extracting shanzhiside methyl ester from Rhizoma Phyllostachys. Background technique [0002] Cordyceps, aliases: big-leaf Cordyceps, Shansuzi, etc., is a plant of the genus Cortella in the Labiatae family. The plant is mainly distributed in Inner Mongolia, Shandong, Shaanxi, Guizhou and other provinces, and is rich in resources. The aerial parts and roots of Corydalis can be used as medicine to treat common cold, cough, phlegm and dyspnea, rheumatic joint pain, lumbago, injury from falls, carbuncle sore and swollen toxin. [0003] The pharmacological activity of Rhizoma Corda is closely related to the active ingredients in Rhizoma Rhizome. At present, there are many studies on the active ingredients of Rhizoma Rhizome. However, due to the complexity of its active ingredients, new research results are still being reported. The main components of Phyllostachys genus are iridoid glycosides, flavonoids, saponins and...
