Process for the preparation of an extract with potent anti-inflammatory, platelet-preventing and antifungal activity from Zingiber Officinale and pharmaceutical compositions containing this extract.

摘要

A method of preparing an extract from Zingiber officinale, which is potent in anti-inflammation and anti-platelet aggregation, includes the following steps: a) preparing a crude liquid from rhizomes of ginger by extraction with an organic solvent or by distillation with steam; b) introducing the crude liquid to a reverse phase chromatography column, and eluting the column with water, a first eluent and a second eluent having a polarity weaker than that of the first eluent but stronger than that of chloroform, so that a first eluate resulting from elution of the first eluent and a second eluate resulting from elution of the second eluent are obtained; c) removing the first eluent from the first eluate by evaporation, so that a first concentrated eluate is obtained and is able to used as the potent extract; and d) removing the second eluent from the second eluate by evaporation, so that a second concentrated eluate is obtained and is able to used as the potent extract.
