Abstract

Disclosed is an improved method for preparing 'Zhenqi Fuzheng' medicine which comprises, extracting Radix Astragali and privet seeds with water and alcohols, depositing the water extract with alcohol so as to precipitate the polysaccharides, subjecting the Radix Astragali extract to macroscopic adsorption resin treatment, removing the mucus substance in the Radix Astragali water extract and gum, and enriching the effective compositions.

Description

technical field [0001] The invention relates to the improvement of the preparation method of the existing drug "Zhenqi Fuzheng". Background technique [0002] Zhenqi Fuzheng medicine is produced by combining plant medicine Astragalus and Ligustrum lucidum in a ratio of nearly 2:1 (weight ratio), which is used to improve immunity and treat leukopenia caused by radiotherapy or chemotherapy. In the prior art, the production process of Zhenqi strengthening medicine is to crush Astragalus membranaceus and Ligustrum lucidum into coarse powder, then decoct with water, then dry the water extract to obtain medicinal powder, and then pack the medicinal powder into capsules to form a commercial drug. Ineffective ingredients such as mucus and gum contained in the medicinal material itself all enter in the extractum when produced with the prior art, but the active ingredients of the medicine are lower. Because contained active ingredient is less, in order to reach the amount of effectiv...
