[Objective] The research aimed to discuss the dormancy mechanism of Panax quinquefolium Linne.seeds.[Method] The germination inhibitors were extracted and isolated by using systematic solvent extraction,separated by TLC.The germination inhibitors were purified by using GC-MS and the structural formula was identified.[Result] 21 kinds of germination inhibitors were identified in the pulp of Panax quinquefolium Linne..[Conclusion] It was proved that the pulp of Panax quinquefolium Linne.contained many germination inhibitors and the inhibition activity showed a reserve relationship with the dilution times.
