ABSTRACT
A new lignan glucoside,(+)-fragransin A_2-4-O-β-D-glucopyranoside(1), has been isolated from the dry root of Paeonia lactiflora by column chromatography on silica gel, Sephadex LH-20, and MCI-gel resin, as well as preparative RP-HPLC. The structure of the new compound was elucidated by spectroscopic data analysis(MS, UV, IR, CD, 1 D and 2 D NMR) and chemical method. Compound 1 showed moderate inhibition against lipopolysaccharide induced nitric oxide production in RAW264.7 macrophages, with an IC_(50) value of 21.3 μmol·L~(-1).
