Monoterpene glycosides from Paeonia veitchii

The EtOH extract of the roots of Paeonia veitchii afforded two new monoterpene glycosides paeonidanin I (1) and paeonidanin J (2), and a new dimeric monoterpene glycoside paeonidanin K (3). Their structures were elucidated on the basis of spectroscopic means and hydrolysis products.
