Nine new monoterpene glycosides (1-9), together with 18 known compounds were obtained from the n-butanol soluble fraction of ethanol extract from Paeonia suffruticosa Andrews. Their structures were determined on the basis of chemical methods and spectroscopic data. The inhibitory effects of these compounds (except compound 6) on nitric oxide (NO) production in lipopolysaccharide-activated macrophages were evaluated. Compounds 1, 21, 23, 25, and 27 showed strong inhibitory activity on NO production with IC50 values of 31.25, 36.13, 12.41, 6.87, and 41.94 mu M, respectively. (C) 2012 Elsevier Ltd.
