Magnolia biondii are used medicinally in China and Japan.
The chemical compositions of volatile components from Magnolia biondii Pamp were determined by steam distillation and headspace solid phase micro-extraction followed by gas chromatography and gas chromatography-mass spectrometry analysis. Fifty-six compounds were identified and the major volatile components were d-camphor, 1,8-cineol, alpha-terpineol and alpha-cadinene. was successfully applied for the first time to the isolation and purification of five lignans including pinoresinol dimethyl ether, magnolin, epi-magnolin A, fargesin, and demethoxyaschantin from M. biondii Pamp after microwave-assisted extraction.
