Embodiment 1

[0036] Embodiment one: the extraction of ginseng polysaccharide

[0037]The extraction method of ginseng polysaccharide of the present invention comprises the following steps:

[0038] A) Collect the root of fresh ginseng, wash it, crush it, pass it through a 80-100 mesh sieve, soak it in water overnight, dry it, and soak it with 75-80% ethanol for extraction or reflux extraction at least 5 times;

[0039] B) After volatilizing the dregs to remove all ethanol, add water to soak, heat to boiling, keep slightly boiling for extraction, and extract at least 5 times in total;

[0040] C) Combine the extracts, concentrate to 1 / 10 volume, add 95% ethanol or absolute ethanol until the alcohol concentration is 40%, centrifuge at 3000rpm for 15 minutes, discard the precipitate, and continue to add 95% ethanol or absolute ethanol to the supernatant , until the alcohol concentration is 60%, centrifuge at 3000rpm for 15 minutes, collect the precipitate, dissolve it in water, refrigerate o...

Abstract

The present invention relates to new preparation form of ginseng polysaccharide, and is especially ginseng polysaccharide powder for injection and its preparation process. The ginseng polysaccharide powder for injection is prepared with the material including ginseng polysaccharide 0.1-20 wt%, medicinal supplementary material 1-15 wt% and water for injection 65-98.9 wt%. The ginseng polysaccharide powder for injection has obviously raised curative effect, fast acting and less sideeffect. It may be used for reducing side effect of radiotherapy and chemotherapy of tumor and as the auxiliary medicine for regulating immunity and treating tumor.

Description

technical field [0001] The invention belongs to the field of medicines and preparations thereof, and relates to a new dosage form of ginseng polysaccharide and a related preparation process. Background technique [0002] Ginseng has a long history of medicinal use in my country. The chemical composition of ginseng is very complex. In addition to ginsenosides, it also contains a variety of sugars, including monosaccharides, oligosaccharides and polysaccharides. There are many research reports on ginsenosides at home and abroad, and the research on ginseng polysaccharides has also made great progress in recent years. [0003] Pharmacological studies have shown that ginseng polysaccharides have immunomodulatory activity, anti-complement activity, antitumor activity, cell protection activity, hypoglycemic activity, etc. , 566-569). Zhao Jun also reported a similar review (Zhao Jun, Advances in Chemical and Pharmacological Research of Ginseng Polysaccharides, Foreign Medicine, ...
