Embodiment 1

[0032] The present embodiment provides a kind of extracting method of rattan notoginseng gum, it comprises the following steps:

[0033] Rough extraction: Take Panax notoginseng tubers with a moisture content of 80% and add them to an acetic acid solution with a mass fraction of 5%. The mass ratio of Panax notoginseng tubers to the acetic acid solution is 1:8, and directly crush the Panax notoginseng tubers to obtain Panax notoginseng tubers. Granules of seven tubers, stirring constantly. Then pass through an 80-mesh sieve to filter out impurities, centrifuge, concentrate and centrifuge the supernatant obtained, remove acetic acid, and obtain the crude colloid of Panax notoginseng.

[0034] Refining: take the ethanol solution with a mass fraction of 95% and mix it with the crude pectin of Panax notoginseng, the volume ratio of the ethanol solution and the crude pectin of Panax notoginseng is 2:1, collect the precipitate by centrifugation, dry the precipitate in vacuum, and the...

Embodiment 2

[0036] The present embodiment provides a kind of extracting method of rattan notoginseng gum, it comprises the following steps:

[0037] Rough extraction: take the vine notoginseng tuber with a water content of 10%, crush it to obtain the granules of the vine notoginseng tuber, pass through a 20 mesh sieve, and then add the acetic acid solution with a mass fraction of 5% to continuously stir, and the vine notoginseng tuber and acetic acid The mass ratio of the solution is 1:15. Then pass through an 80-mesh sieve to filter out impurities, centrifuge, concentrate and centrifuge the supernatant obtained, remove acetic acid, and obtain the crude colloid of Panax notoginseng.

[0038] Refining: take the ethanol solution with a mass fraction of 95% and mix it with the crude pectin of Panax notoginseng, the volume ratio of the ethanol solution and the crude pectin of Panax notoginseng is 2:1, collect the precipitate by centrifugation, dry the precipitate in vacuum, and then Then put...

Embodiment 3

[0040] The present embodiment provides a kind of extracting method of rattan notoginseng gum, it comprises the following steps:

[0041] Rough extraction: Take Panax notoginseng tubers with a moisture content of 70% and add them to an acetic acid solution with a mass fraction of 10%. The mass ratio of Panax notoginseng tubers to the acetic acid solution is 1:10, and directly crush the Panax notoginseng tubers to obtain Panax notoginseng Granules of tubers, stirring constantly. Then pass through an 80-mesh sieve to filter out impurities, centrifuge, concentrate and centrifuge the supernatant obtained, remove acetic acid, and obtain the crude colloid of Panax notoginseng.

[0042] Refining: take the ethanol solution with a mass fraction of 97% and mix it with the crude pectin of Panax notoginseng, the volume ratio of the ethanol solution and the crude pectin of Panax notoginseng is 3:1, collect the precipitate by centrifugation, dry the precipitate in vacuum, and then Then put ...

Abstract

The invention relates to an extraction method of Anredera cordifolia colloid, comprising the steps of performing crude extracting, to be specific, mixing 2-10% by mass of acetic acid solution and particles of Anredera cordifolia tuber, screening the mixture, centrifuging, concentrating and centrifuging to obtain supernate that is crude Anredera cordifolia colloid; refining, to be specific, mixingethanol solution and the crude Anredera cordifolia colloid, centrifuging, drying precipitate from centrifuging treatment, dialyzing, and drying the dialyzed product to obtain Anredera cordifolia colloid. The extraction method of the Anredera cordifolia colloid has the advantages that oxidative fading of Anredera cordifolia during extraction is effectively prevented, and the Anredera cordifolia colloid is pure, may act as a traditional Chinese gel matrix and is effective in assisting in treating rheumatism and bone injuries.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine pharmacy, in particular to a method for extracting vine notoginseng gum. Background technique [0002] Rattan notoginseng, a plant of the genus Lakwai in the genus Lakniaceae, is slightly bitter in taste, warm in nature, and has the function of promoting blood circulation and nourishing blood. It is a commonly used traditional Chinese medicine. Rattan notoginseng can be used to invigorate the kidney and strengthen the waist, dissipate blood stasis and reduce swelling, and mainly treat waist and knee arthralgia, weakness after illness, bruises and fractures. [0003] Rattan notoginseng jelly is extracted from rattan notoginseng, which can be used as the matrix of traditional Chinese medicine gel, and has a good auxiliary treatment effect on rheumatism and bone injury diseases. However, the traditional extraction method of Panax notoginseng gum often leads to oxidation and disc...
