Abstract: | By monitoring the effects on HCl/ethanol-induced gastric lesions in rats, a new antiulcer principle named 6-gingesulfonic acid was isolated from Zingiberis Rhizoma, the dried rhizome of Zingiber officinale Roscoe (cultivated and processed in Taiwan) together with three new monoacyldigalactosylglycerols named gingerglycolipids A, B and C. Their chemical structures were elucidated on the basis of chemical and physicochemical evidence. 6-Gingesulfonic acid showed more potent anti-ulcer activity than 6-gingerol and 6-shogaol. |
