Monoterpene Glycosides from the Roots of Paeonia lactiflora

A new monoterpene glycoside, together with nine known ones, 3-O-methylpaeoniflorin,mudanpioside J, paeoniflorin, benzoylpaeoniflorin, oxypaeoniflorin, benzoyloxypaeoniflorin,oxybenzoylpaeoniflorin, albiflorin and lactiflorin, was isolated from the roots of Paeonia lactiflora Pall.. The structure of the new compound was elucidated as galloylalbiflorin by the spectroscopic evidence including ESI-MS, 1D- and 2D-NMR spectra.
