Monoterpene glycosides with anti-inflammatory activity from Paeoniae Radix

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...
