Embodiment 1

[0013] The extraction method of acacia saponin of the present embodiment comprises the following main steps:

[0014] (1), crude extraction: take the medicinal material of Aegypti sinensis, pulverize, add 15 times the volume of 60% ethanol, reflux extraction for 3 hours, extract 3 times, combine the extracts, recover the ethanol, and concentrate the liquid into a dilute extract with a relative density of 1.20 ointment, that is, the crude extract of Aegia sinensis;

[0015] (2), refining for the first time: passing the crude extract of Aegypti japonica obtained in step (1) through a D101 macroporous adsorption resin column, eluting successively with water, 10% ethanol, and 30% ethanol to remove the soluble polar solvent impurities, discard water eluate, 10% ethanol eluate, 30% ethanol eluate; then elute with 70% higher concentration ethanol, collect this higher concentration ethanol eluate, recycle ethanol, concentrate To a relative density of 1.25, to obtain the first refinin...

Embodiment 2

[0019] The extraction method of acacia saponin of the present embodiment comprises the following main steps:

[0020] (1), crude extraction: take the medicinal material of Aegypti sinensis, pulverize it, add 12 times the volume of 70% ethanol, reflux extraction for 4 hours, extract twice, combine the extracts, recover the ethanol, and concentrate the liquid into a dilute extract with a relative density of 1.25 ointment, that is, the crude extract of Aegia sinensis;

[0021] (2), refining for the first time: passing the crude extract of Aegypti japonica obtained in step (1) through a D101 macroporous adsorption resin column, eluting successively with water, 10% ethanol, and 30% ethanol to remove the soluble polar solvent impurities, discard the water eluate, 10% ethanol eluate, and 30% ethanol eluate; then elute with 80% higher concentration ethanol, collect this higher concentration ethanol eluate, recycle ethanol, concentrate It is 1.22 to relative density, obtains the extra...

Embodiment 3

[0025] The extraction method of acacia saponin of the present embodiment comprises the following main steps:

[0026] (1), crude extraction: take the medicinal material of Aegypti sinensis, pulverize, add 10 times the volume of 75% ethanol, reflux extraction for 3.5 hours, extract 2 times, combine the extracts, recover the ethanol and concentrate the liquid into a dilute extract with a relative density of 1.22 ointment, that is, the crude extract of Aegia sinensis;

[0027] (2), refining for the first time: passing the crude extract of Aegypti japonica obtained in step (1) through a D101 macroporous adsorption resin column, eluting with water, 10% ethanol, and 30% ethanol successively to remove the soluble polar solvent impurities, discard water eluate, 10% ethanol eluate, 30% ethanol eluate; then elute with 90% higher concentration ethanol, collect this higher concentration ethanol eluate, recycle ethanol, concentrate It is 1.20 to relative density, obtains the extracting so...

Abstract

The invention discloses a method for extracting glaucescent fissistigma root saponins, comprising the steps of crude extraction, primary fining, further refining and the like. In an extractive extracted from Marsdenia tenocissima (Roxb) Wight et Arn. of a Marsdenia R.Br. plant, the content of the glaucescent fissistigma root saponins is higher and can reach above 90%, and the yield is also higher.

Description

technical field [0001] The invention relates to the technical field of extracts of traditional Chinese medicines, in particular to a method for extracting black bone saponin. Background technique [0002] The traditional Chinese medicine Ebony Teng is the cane of Marsdenia tenocissima (Roxb) Wight et Arn., which is a plant of the genus Marsdenia R.Br. It was first published in "Southern Yunnan Materia Medica". Bitter in nature and slightly cold, it has the functions of anti-inflammatory, heat-clearing and detoxifying, relieving cough and asthma, dispelling stagnation and relieving pain, etc. It is mainly produced in Yunnan. It contains a variety of steroidal ester glycosides, alkaloids, organic acids, polysaccharides, resins and pigments and other chemical components. It is traditionally used for cough and asthma, phlegm cough and asthma, and mainly treats bronchitis and bronchial asthma. It has been recorded in the "Drug Standards of Yunnan Province" and "Chinese Pharmaco...
