Objective: To research the reason of seed dormancy in Cinnamomum Migao. Method: We use certain concentration of hydrogen peroxide treatment Migao fruit, it can make Migao seed germination rate increased from zero to more than forty percent. On the basis of this, the changes of chemical constituents in the fruit of Migao were compared before and after treatment with hydrogen peroxide. The chemical constituents in the fruit of Migao were determined to inhibit the seed germination. And verification experiments show that these components play an inhibitory effect on seed germination. Result: After hydrogen peroxide treatment Migao fruit, there are six kinds of chemical composition completely disappeared. Conclusion: First, inhibition of Migao seed germination chemical composition is not one, but many, they exist in the meter Migao volatile oil;Second, hydrogen peroxide can destroy partially inhibited seed germination chemical composition, thereby increasing the number of Migao seeds germinate. These easily destroyed chemical compositions of hydrogen peroxide are 2,3-Dehydro-1,8-Cineale, Cis-Sabinene hydrate, β-Cubebene, α-Humulene, α-Gurjunene, and Ledene. They may be all or part participated in the inhibition of seed germination.
