Abstract

Two new monoterpenoid glycosides, trans-1,8-cineole-3,6-dihydroxy-3-O-β-D-glucopyranoside (1), and 5,9-dihydroxy borneol 2-O-β-D-glucopyranoside (2), together with four known monoterpenoid glycosides (3-6), were isolated from the water-soluble constituents of the fresh rhizome of Tongling White Ginger (Zingiber officinale). Their structures were decisively elucidated by spectroscopic analysis. In vitro tests for antimicrobial activity showed that compounds 1 and 3 possess significant activity against two Gram-positive organisms, Staphylococcus aureus and Staphylococcus epidermidis.

Keywords: Zingiber officinale; Zingiberaceae; antimicrobial activity; monoterpenoid glycosides.
