Problems solved by technology

The weak point of this technique is that adopting 75% ethanol can not extract the polysaccharide active components that Acanthopanax senticosus has to improve immunity, because the polysaccharide components are insoluble in 75% ethanol, in addition, to adopting 75% to extract The effective component that goes out is also without purification process, makes the content of active component wherein not high, therefore, this is also the problem to be solved by the method of the present invention
Chinese patent CN1053817C reports the preparation method of Acanthopanax anticanax extract and the injection containing the extract and freeze-dried powder injection, and its preparation process also adopts macroporous adsorption resin, but it only mentions the use of macroporous resin for decolorization, and The specific test method was not specified, and the reported Acanthopanax injection and freeze-dried powder did not retain pharmacologically active polysaccharide components, because the extraction method used was also the traditional water extraction and alcohol precipitation process , water extraction can extract polysaccharides, but alcohol precipitation process will remove polysaccharides
Chinese patent CN00123053 also discloses the production process of Acanthopanax senticosus essence extract, which uses 50%-80% ethanol to leach first, then heats and extracts with 50%-80% ethanol, and then passes through a macroporous adsorption resin column. Before applying the macroporous adsorption resin, the solution is clarified by adding water and standing for refrigeration, so as to prevent particles in the extract from contaminating and clogging the macroporous resin. It takes time to stand in refrigeration and the production cycle is long. For this, the present invention adopts high-speed centrifugation , has the advantages of short time, high efficiency, and beneficial to industrialized production; it uses 10-30% ethanol to elute the macroporous resin after loading the sample, and can only elute the more polar glycoside components, while for For example, the isofrindine and saponins in Acanthopanax are difficult to elute, and Acanthopanax saponins also have good physiological activities (Wang Linli, Zhang Jiabi. The pharmacological effects and clinical treatment progress of Acanthopanax [J]. China Pharmaceutical Industry, 2003, 12 (4): 79-80); In addition, the most important thing is that it adopts 50%-80% ethanol extraction, and the column purification of the macroporous adsorption resin fails to extract the important Physiologically active Acanthopanax polysaccharides extracted
(Liu Baozhu, Peiyuehu Acanthopanax pharmacological research progress [J]. Journal of Shenyang Pharmaceutical University, 2002, 19 (2): 143-146); moreover, no lyophilized powder was added to the prepared lyophilized powder injection. The use of excipients is not conducive to the freeze-drying of the product. Without the addition of excipients, the resolubility of the product with water for injection is not very good, but after adding the freeze-dried excipients, the resolubility of the product is good. After adding water for injection , lyophilized powder can dissolve quickly

Abstract

The invention discloses a method for preparing acanthopanax injection, which consists of employing alcohol and water extraction method to extract the glycosides components and polysaccharides active constituents in acanthopanax root, refining glycosides components through macroscopic adsorption resin column purifying, removing impurities from polysaccharides component through water extraction alcohol depositing method, removing small molecules through hollow fiber column hyperconcentration, the effective component with activity in the acanthopanax root can be fully preserved.

Description

[0001] Field [0002] The invention belongs to the field of traditional Chinese medicine pharmacy, and in particular relates to a method for preparing Acanthopanax senticosus injection preparation. Background technique [0003] Acanthopanax is the dried root, rhizome or stem of Acanthopanax acanthopanax, which has the effects of nourishing Qi, invigorating the spleen, tonifying the kidney and calming the nerves. Acanthopanax contains active ingredients such as eleutherosides A, B, C, D, E, isoferidin and water-soluble acanthopanax polysaccharides. According to literature reports, Acanthopanax has strong effects of promoting blood circulation and removing blood stasis, dredging meridians and activating collaterals, can dilate blood vessels, improve blood flow in heart, brain, kidney and other substantial organs, and increase tissue tolerance to hypoxia. Can significantly remove reactive oxygen species, reduce platelet aggregation, dilate coronary arteries, improve myocardial m...
