摘要:
A method of treating a patient suffering a disease associated with Trichophyton mentagrophytes or Pityrosporum ovale by applying topically an anti-fungal pharmaceutical composition which is prepared from Zingiber officinale, includes the following steps: preparing a crude liquid from rhizomes of ginger by extraction with an organic solvent or supercritical CO2, or by distillation with steam; 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; removing the first eluent and the second eluent from the first eluate and the second eluate by evaporation, respectively, so that a first concentrated eluate and a second concentrated eluate are obtained as the potent extract.

A pharmaceutical composition contains a therapeutically effective amount of an active ingredient, in admixture with a pharmaceutically acceptable carrier or diluent for the active ingredient, in which the active ingredient is i) a polar solvent extract of Polygala, the polar solvent being water or a mixture of water and methanol or ethanol; ii) an aqueous fraction resulting from an extraction of the polar solvent extract with an organic solvent; iii) an organic eluate by introducing the polar solvent extract or the aqueous fraction into a reverse phase chromatography column, and eluting the column with water and an organic solvent; or iv) a filtrate having a molecular mass less than 30000 in the organic eluate.

An antitussive composition is provided. A pharmaceutical composition for relieving, preventing and/or treating a cough includes a sufficient amount of the Morus australis Poir extract as an active component. The effective Morus australis Poir extract is prepared by extracting the root-bark of the Morus australis Poir with water, ethanol, acetone, ethyl acetate, or a combination thereof. The crude extract can be further fractioned by ultrafiltration or reverse phase column.

The present invention discloses a new use of a potent product extracted from rhizomes of Zingiber officinale in treating a disease associated with Helicobacter pylori such as gastritis, gastric ulcer or duodenal ulcer in a patient. The potent product is prepared by a process including the steps of a) preparing a crude extract from rhizomes of Zingiber officinale, said crude extract comprising 6-gingerol and 6-shogaol; b) introducing the crude extract to a reverse phase chromatography column, and eluting the column with a first eluent having a polarity lower than water to obtain a first potent fraction or a second eluent having a polarity lower than that of the first eluent to obtain a second potent fraction. Preferably, the second potent fraction is substantially free of both 6-gingerol and 6-shogaol.

The potent product is prepared by a process including the steps of a) preparing a crude extract from rhizomes of Zingiber officinale, said crude extract comprising 6-gingerol and 6-shogaol; b) introducing the crude extract to a normal phase chromatography column, and eluting the column with a first eluent having a polarity lower than that of a mixture of n-hexane and ethyl acetate in a weight ratio of 6:4 to obtain a potent fraction. Preferably, the potent fraction is substantially free of both 6-gingerol and 6-shogaol.
