Method for extracting and preparing arthritisChinese patent medicine from ginger

Abstract

The invention provides a method for extracting and preparing an arthritisChinese patent medicine from ginger. The method is mainly characterized in that the arthritisChinese patent medicine is prepared by an extract of the ginger (fresh ginger and dry ginger), and content of an effective part (consisting of volatile components) in the extract is greater than 50%; the medicine has the effects of warming and activating merdian, resisting inflammation and alleviating pain and the like, and is used for preventing and treating (rheumatoid) rheumatic arthritis; and content of an effective part of apreparation prepared by the extract is greater than 50%. A preparation method for the extract is characterized by comprising a squeezing method, a steam distillation method (comprising a co-water distillation method), a supercritical carbon dioxide extraction method, an organic solvent extracting method, a water-adding grinding method and a column chromatography method. The extract thereof can beprepared as any medical dosage forms, and applied for preparing the medicine for preventing and treating rheumatism. The medicine composition is capable of overcoming limitation that most of the medicines for treating the rheumatism are a crude medicine single-prescription or compound-prescription water decoction preparation of the traditional medicines, and providing a pure traditional Chinese medicine modern pharmaceutical preparation with exact curative effect, safety and convenience, small side effect, and low price and a preparation technology.

AI Technical Summary

Problems solved by technology

There are multiple Chinese medicine preparations for the treatment of (like) rheumatoid arthritis. They all have a good effect on treating internal rheumatism, can control the disease, and relieve symptoms, but there are still deficiencies: first, the effective parts (active ingredients) of Chinese medicines The problem of extraction, separation and preparation methods, because they are the material basis for the efficacy of traditional Chinese medicine and the bottleneck of the modernization of traditional Chinese medicine

However, traditional processes such as soaking, decoction, and percolation are still used at present, making it difficult to prepare the extracts into effective parts (active ingredients) with quantitative indicators; followed by quality standards, anti-rheumatic Chinese patent medicines are mostly compound preparations or traditional Chinese medicines In bold, no quality standards have been proposed or established for the control of raw materials, extracts and finished preparations
