Marruboside, a New Phenylethanoid Glycoside from Marrubium Vulgare L

Abstract

A new phenylethanoid glycoside, marruboside, has been isolated from the aerial parts of Marrubium vulgare L. Its structure was established as 3,4-dihydroxy- g -phenylethoxy- O- [ g - d -apiofuranosyl-(1 M 2)- f - l -rhamnopyranosyl-(1 M 3)]-[ g - d -apiofuranosyl-(1 M 6)]-4- O -caffeoyl- g - d -glucopyranoside, on the basis of spectroscopic evidence.
