Six new monoterpene glycosides, named 6'-O-nicotinoylalbiflorin (1), 4'-O-vanillylalbiflorin (2), paeonidanin L (3), paeoniflorigenin-1-O-β-d-xyloside (4), 6'-(2-hydroxypropanoyl)-paeoniflorin (5), oxylactiflorin (6), together with 16known ones (7-22) were isolated from the 70% ethanol extract of Paeoniae Radix. Their structures were elucidated based on spectroscopic analysis (1D and 2D NMR, HRESIMS, IR and UV), chemical evidences and comparison with literatures. The inhibitory effects of all the isolates were evaluated against lipopolysaccharide (LPS) stimulated PGEproduction in RAW 264.7 macrophages.
