Abstract:
Monoterpene glycosides (1-5, and 7), together with 14 known compounds, were isolated from the methanol extract of the roots of Paeonia hybrida. These compounds included a paeoniflorin-related glycoside with a hybrid structure of paeoniflorin and paeonovicinoside (1), a monoterpene glucoside biogenetically related to lactiflorin (2), a paeoniflorin-related monoterpene (3), arbiflorin-related monoterpenes (4 and 5), and a tymol-related monoterpene glycoside (7). Their structures were elucidated by extensive spectroscopic examinations.
