Three new acetylated and one known kaempferol glycosides have been isolated from the rhizomes of Zingiber zerumbet and their structures determined to be the 3-O-(2-O-acetyl-alpha-L-rhamnopyranoside), 3-O-(3-O-acetyl-alpha-L-rhamnopyranside), 3-O-(4-O-acetyl-alpha-L-rhamnopyranoside) and 3-O-alpha-L-rhamnopyranoside on the basis of spectroscopic methods.
