Monoterpene Glucosides from Paeonia lactiflora.

J Nat Prod. 2009 Apr 29; Wang HB, Gu WF, Chu WJ, Zhang S, Tang XC, Qin GWFour new "cage-like" monoterpene glucosides (1-4) were isolated from Paeonia lactiflora. The structures of these compounds were established by spectroscopic methods, mainly 1D and 2D NMR, and mass spectrometric analysis. Compound 4 exhibited moderate cell-protective activity against hydrogen peroxide-induced PC12 cell damage.
