Embodiment 1

[0026] The preparation of embodiment 1 polysaccharide composition of the present invention

[0027] Weigh 100 g of aconite and 400 g of licorice, add 20 times the volume of water, soak and extract once at 90°C for a total of 8 hours, and collect the filtrate. Evaporate and concentrate under reduced pressure at 60°C to 15% of the original volume, add 95% ethanol aqueous solution to the concentrated solution until the ethanol concentration is 80%, put it in a refrigerator at 4°C overnight, filter with suction, and wash the precipitate with absolute ethanol solution and acetone in turn. Once, dried at 60°C to obtain 13.5 g of the extract of the present invention.

Embodiment 2

[0028] The preparation of embodiment 2 polysaccharide composition of the present invention

[0029] Weigh 100 g of aconite and 400 g of licorice, add 10 times the volume of water, soak and extract twice at 70°C for 4 hours each time, and collect the filtrate. Evaporate and concentrate under reduced pressure at 60°C to 15% of the original volume, add 95% ethanol aqueous solution to the concentrated solution until the ethanol concentration is 80%, put it in a refrigerator at 4°C overnight, filter with suction, and wash the precipitate with absolute ethanol solution and acetone in turn 2 times, drying at 60°C to obtain 10.2 g of the extract of the present invention.

Embodiment 3

[0030] Embodiment 3 Preparation of the polysaccharide composition of the present invention

[0031] Weigh 100 g of aconite and 400 g of licorice, add 10 times the volume of water, soak and extract at 80°C for 3 times, each time for 6 hours, and collect the filtrate. Evaporate and concentrate under reduced pressure at 60°C to 15% of the original volume, add 95% ethanol aqueous solution to the concentrated solution until the ethanol concentration is 80%, put it in a refrigerator at 4°C overnight, filter with suction, and wash the precipitate with absolute ethanol solution and acetone in turn. Once, dried at 60°C to obtain 24.1 g of the extract of the present invention.

Abstract

The invention discloses a preparation method of a radix aconiti lateralis preparata-licorice root polysaccharide extract. The preparation method comprises: a, taking 1-4 parts by weight of radix aconiti lateralis preparata, and 4 parts by weight of licorice root; b, adding 10-30 times the volume of water, carrying out warm immersion extraction for 4-8 h at a temperature of 70-90 DEG C, and concentrating the extraction liquid; c, adding ethanol to the concentrated liquid obtained in the step b while stirring; d, standing, precipitating, carrying out suction filtration, and collecting the filtration residue; and e, washing the filtration residue, and drying so as to obtain the product. According to the present invention, with the method, the polysaccharide can be extracted from the radix aconiti lateralis preparata and the licorice root to the maximum, wherein the polysaccharide extraction rate is up to 6.4%. The invention further provides the radix aconiti lateralis preparata-licorice root polysaccharide extract obtained according to the method, wherein the efficacy experiment results prove that the two polysaccharide components complement each other and synergistically act, have the significant improved anti-oxidation effect and the immunity enhancing effect, do not inhibit the proliferation of normal liver cells, further have advantages of excellent biosafety and good clinical application prospects.

Description

technical field [0001] The invention relates to an extract of aconite licorice polysaccharide and a preparation method thereof, belonging to the field of medicine. Background technique [0002] Aconitum comes from the roots and processed products of Aconitum carmichaeli Debx. in Ranunculaceae. Mild cold pulse, impotence, cold uterus, cold pain in trusted subordinates, vomiting and diarrhea due to deficiency and cold, edema due to yin and cold. [0003] Licorice is the root and rhizome of Glycyrrhiza uralensis Fisch, G. glabra L. or G. inflata Batalin. Relieving spasm and relieving pain, clearing heat and detoxification, and harmonizing the properties of medicines, it is mostly used for qi deficiency syndromes and attenuation. [0004] In TCM clinical practice, aconite, licorice, and dried ginger are commonly used to form yang-recovering medicines to treat symptoms such as weak yang qi. As for the research on the combined use of aconite and licorice, at present, it mainly ...
