Problems solved by technology

This application uses water or an organic solvent as a solvent to extract the active ingredients in Phyllanthus phylloxera. This method is simple, but water extraction will simultaneously extract a large amount of macromolecular substances such as proteins, tannins, and organic pigments. The removal of impurities in the solution has seriously affected the pharmacological effects of the active ingredients of Phyllostachys phylloxera
The application number is 200410039386.5 in the patent application using alcohol or acetone as the extraction solvent to extract polyphenolic compounds from Phyllanthus phylloxera. The other active ingredients of Phyllostachys phylloxera have not been elaborated, which has seriously affected the therapeutic effect of Phyllanthus phylloxera in treating hepatitis B

Abstract

The invention discloses a preparing method for common leafflower herb oral solid preparation and its application. The effective components of the common leafflower herb are extracted by three solvent with different polarity of n-hexane, ethanol and water. Then the main medicine is obtained by refining respective extracting parts and combinating obtained effective part group. The invention adds some proper medical accessory to produce the common leafflower herb oral solid preparation which has a stronger antivirus function and repairing liver injury function. The invention fully extracts the effective components of the common leafflower herb, has a low cost and low pollution and is suitable for industry production. Pharmacological experiments prove the inventive common leafflower herb oral solid preparation has a good hepatitis B virus resistance function.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine pharmacy, and in particular relates to a preparation method and application of an oral solid preparation of Phyllostachys phylloxera. Background technique [0002] Phyllanthus urinaria is the dry whole plant of Phyllanthus urinaria L. in the Euphorbiaceae family. It is cool in nature and slightly bitter. It is mainly used in the treatment of infectious hepatitis, enteritis, dysentery, nephritis edema, malnutrition in children, etc. Studies have shown that Phyllostachys chinensis contains flavonoids, lignans, terpenes, tannins, alkaloids and other compounds. Phyllostachys phylloxera has strong anti-hepatitis B virus and liver protection activity, but there are different opinions on the research on the specific anti-hepatitis B virus active ingredients in Phyllostachys pratense. Or the pharmaceutical composition of the extract of Phyllostachys phylloxera for the treatment of h...
