Guided by PAF induced platelet aggregation, six active lignins were isolated from the flower buds of Magnolia biondii and identified as fargesin, demethoxyaschantin, aschantin, pinoresinol dimethyl ether, magnolin, lirioresinol-B dimethyl ether. The 13CNMR and CD data were reported and the
The present study aims to investigate the lignans from the flower buds of Magnolia biondii. The isolation and purification of the compounds were performed by column chromatographies on Diaion HP-20, silica gel, and Sephadex LH-20, combined with semi-preparative HPLC. Their structures were elucidated
