FIVE MONOTERPENE GLYCOSIDES FROM ZINGIBERIS RHIZOME(SHOKYO)

摘要

Five monoterpene glycosides were isolated from Zingiberis rhizome(Japanese name: Shokyo).They were characterized to be(+)-angelicoidenol 2-OMICRON-beta-D-glucopyranoside(1),(+)-angelicoidenol 2-OMICRON-beta-D-glucopyranosido-5-OMICRON-beta-D-g!ucopyranoside(2),(+)-angelicoidenol 2-OMICRON-beta-D-apiofuranosyl(l->6)-beta-D-glucopyranoside(3),(+)-angelicoidenol 2-OMICRON-[6'-OMICRON-S-3-hydroxy-3-methylglutaryl]-|3-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.
