The cortex root of Paeonia ostii, is used as a traditional Chinese medicine for treating female diseases. Phytochemical investigation of the water-soluble fraction of the plant led to the isolation of two new acetoisovanillone glycosides: acetoisovanillone-3-O-β-D-glucopyranoside (1) and 2-hydroxy-acetoisovanillone-3-O-β-D-glucopyranoside (2). Their structures were elucidated by extensive spectroscopic methods.
