ABSTRACT
Objective To investigate the chemical constituents and activities of Linum usitatissimum L.aboveground. Meth-ods The chemical constituents were separated through silica gel,ODS,Sephadex LH-20,and semi-preparative RP-HPLC chroma-tography and identified by optical rotation and spectroscopic analysis. All of the isolates were evaluated for their inhibitory activities by the luciferase assay. Results Eight dibenzylbutyrolactone lignans were separated from L. usitatissimum and identified as(-)-hinoki-nin(1),(-)-bursehernin(2),(-)-dimethylmatairesinol(3),(-)-yatein(4),(-)-thujaplicatin trimethyl ether(5),nemerosin (6),(+)-E-7,8-dehydromatairesinol dimethyl ether(7),and E-7,8-dehydrothujaplicatin trimethyl ether(8),respectively. Conclu-sion Compounds 7 and 8 were isolated from L. usitatissimum for the first time,and NMR spectral data of compound 8 were reported for the first time. Compounds 1 and 3 showed moderate inhibitory activities on IL-6/STAT3 signaling pathway with IC50 values of 42.12 and 43.43μmol/L,respectively.
