Problems solved by technology

Most of them use syringin as the quality control standard, and there are some injection varieties that only have a single effective fraction of total flavonoids, and the existing technology is mostly based on organic solvent extraction, which not only has high production costs, but also has relatively high pollution in industrialized production. Large, and there are very few reports on extracts containing total glycosides in effective parts
In the prior art, there is also a method of extracting the active ingredients of Acanthopanax senticosus using a certain mass fraction of ethanol as the extraction solvent, but the prepared active ingredient extract also has defects such as low content of active ingredients.

Abstract

The present invention discloses an extract of acanthopanax effective part, a preparation method thereof and an application thereof. In the acanthopanax extract of the present invention, total glycoside takes 20 to 64wt percent of the gross extract; total flavone takes 20 to 65wt percent of the gross extract; total glycoside total flavone takes 50 to 90wt percent of the gross extract. The preparation method of the acanthopanax effective part of the present invention is simple and convenient and causes little environmental pollution; the extracting and separating carrier can be used repeatedly for a plurality of times; the present invention has low cost and is applied to mass industrialization production.

Description

technical field [0001] The present invention relates to an extract of the effective part of a single plant, in particular to the extract of the effective part of Acanthopanax and its preparation method. Diseases, improving human immunity, anti-tumor, anti-radiation, and reducing the damage of radiation or chemotherapy drugs to the body belong to the field of traditional Chinese medicine. Background technique [0002] Acanthopanax is the dry root and rhizome of Acanthopanax senticosus (Puper.er Maxim) Harms, a plant of Araliaceae. Acanthopanax is a typical medicinal plant in Northeast my country. It is pungent, slightly bitter, warm in nature and non-toxic. Mainly distributed in my country's Heilongjiang, Jilin, Liaoning, Hebei and other places. [0003] Acanthopanax is a plant medicine with high medicinal value and a wide range of applications. In recent years, Chinese medicine workers have discovered that Acanthopanax has the effects of nourishing qi and strengthening the...
