METHODS: The volatile components were extracted from hull and seeds of Magnolia grandiflora by steam distillation and the chemical components of them were identified by GC-MS .RESULTS : One hundred and eleven compounds were extracted from the hull, seventy-eight compounds were identified, accounting for 56.54%of the total volatile oil, and eighty-nine compounds were extracted from seed , fifty-eight compounds were identified, accounting for 46.02 % of the total volatile oil. Twenty-one compounds were common in both of hull and seeds. CONCLUSION:The results of the studies can be referenced when the hull and seeds of Magnolia grandiflora need to be further studied.
