Abstract

Five monoterpene glycosides were isolated from Zingiberis rhizome (Japanese name: Shokyo). They were characterized to be (+)-angelicoidenol 2-O-β-D-glucopyranoside (1), (+)-angelicoidenol 2-O-β-D-glucopyranosido-5-O-β-D-glucopyranoside (2), (+)-angelicoidenol 2-O-β-D-apiofuranosyl(1→6)-β-D-glucopyranoside (3), (+)-angelicoidenol 2-O-[6’-O-S-3-hydroxy-3-methylglutaryl]-β-D-glucopyranoside (4) and its methyl ester (5), respectively, by means of spectroscopic and chemical methods. Of them, the new glycosides (2, 3 and 4) were named zingiberosides A, B and C, respectively.
