Abstract: 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 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.

Abstract: 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.

Abstract: A polygalatenoside useful as an antidepressant agent having the formula is disclosed: wherein R, R? and R? independently are H or R1, provided that R, R? and R? are not all H, wherein R1 is wherein R2 is hydrogen, C1-C6 alkyl, C1-C6 alkoxy or halogen; or a pharmaceutically acceptable salt thereof. Preferably, R2 is H.
