Two new monoterpene glucosides from Paeonia lactiflora Pall.

Abstract

Two new monoterpene glucosides, 4′-O-benzoylpaeoniflorin (1) and 4-O-galloylalbiflorin (2), were isolated from the 60% ethanol extract of the dried roots of Paeonia lactiflora Pall. Their structures were established on the basis of spectroscopic data.
