Embodiment 1

[0024] The refining method is:

[0025] a. Take the Chinese medicinal material Polygonum multiflorum, cleanly select and break;

[0026] b. Add 8 times the amount of water to extract twice, each time for 2 hours, and filter the extract to obtain a water extract.

[0027] c. Filter the water extract obtained in step b with an inorganic ceramic membrane provided by French TAMI company. The pore size of the inorganic ceramic membrane is 50nm. / s, when the remaining original volume of the extract is 10%, add the same volume of water, and continue to filter until the remaining original volume of the extract is 10%.

Embodiment 2

[0032] The refining method is:

[0033] a. Take the Chinese medicinal material Polygonum multiflorum, cleanly select and break;

[0034] b. Add 6 times the amount of water to extract twice, each time for 3 hours, and filter the extract to obtain a water extract.

[0035] c. Filter the water extract obtained in step b with an inorganic ceramic membrane provided by French TAMI company. The pore size of the inorganic ceramic membrane is 30nm. / s, when the remaining original volume of the extract is 10%, add the same volume of water, and continue to filter until the remaining original volume of the extract is 10%.

Embodiment 3

[0040] The refining method is:

[0041] a. Take the Chinese medicinal material Polygonum multiflorum, cleanly select and break;

[0042] b. Add 10 times the amount of water to extract twice, each time for 1 hour, and filter the extract to obtain a water extract.

[0043] c. Filter the water extract obtained in step b with an inorganic ceramic membrane provided by French TAMI company. The pore size of the inorganic ceramic membrane is 200nm. / s, when the remaining original volume of the extract is 10%, add the same volume of water, and continue to filter until the remaining original volume of the extract is 10%.

Abstract

The invention discloses a refine method for polygonum multiflorum water extract. The polygonum multiflorum has the efficacies of nourishing liver and kidney, benefiting essence and blood, blackening beard and hair and strengthening muscles and bones. The method adopts inorganic ceramic membrane filtration to refine the Polygonum multiflorum water extract, has high transferring efficiency of effective components, can be industrially produced, has simple feed liquid process; and the inorganic ceramic membrane is convenient to clean, and can be recycled.

Description

technical field [0001] The invention relates to a method for refining the water extract of Polygonum multiflorum, in particular to a method for refining the water extract of Polygonum multiflorum through inorganic ceramic membrane filtration. Background technique [0002] The main purpose of the production process of traditional Chinese medicine preparations is to enrich the active ingredients and remove invalid impurities. The refining of traditional Chinese medicine is mostly based on the polarity difference between components (solvent precipitation or extraction, adsorption separation, etc.) Component loss or heat damage, resulting in reduced efficacy, etc. Inorganic ceramic membrane separation technology is based on the principle of sieving, which can separate suspended particles of 0.05-10 μm and some macromolecular impurities in the solution. Inorganic ceramic membranes for traditional Chinese medicine separation are mostly Al 2 o 3 The ceramic membrane has a pore ...
