Acylated flavonoid and phenylethanoid glycosides from Marrubium velutinum

From the aerial parts of Marrubium velutinum, one acylated flavonoid glycoside, chrysoeriol 7- O-(3″,6″-di- O- E- p-coumaroyl)-β- d-glucopyranoside, and two tetrasaccharidic phenylethanoid glycosides, velutinosides I-II, have been isolated together with ten known flavonoids and seven known phenyleth...

Description
Summary:From the aerial parts of Marrubium velutinum, one acylated flavonoid glycoside, chrysoeriol 7- O-(3″,6″-di- O- E- p-coumaroyl)-β- d-glucopyranoside, and two tetrasaccharidic phenylethanoid glycosides, velutinosides I-II, have been isolated together with ten known flavonoids and seven known phenylethanoid glycosides. The structures of the isolated compounds were established by means of NMR, MS, and UV spectral analyses. An acylated flavonoid glycoside, chrysoeriol 7- O-(3″,6″-di-O-E-p-coumaroyl)-β-D-glucopyranoside, and two tetrasaccharide phenylethanoid glycosides, velutinosides I-II, have been isolated from the aerial parts of Marrubium velutinum.
