A total of 52 compounds have been identified in the fresh China wingnut ( Pterocarya stenoptera C.DC) extracted by SPME and GC-MS. The principal components are nerolidol (15.54%), germacrene A (14.22%), trans-caryophyllene (10.19%) ,7,8,9,10-tetrahydro-S-diazole(3,4-A)-phthalazine (8.59%)and hexadecanoic acid (6.22%).Varieties of 32compounds have been identified in the wilts China wingnut extracted by SPME. The main components are α-bisabolene(17.69%), nerolidol (16.64%), trans-caryophyllene ( 14.26% ) and α-selinene (9.14%). Varieties of 31 compounds have been identified in the dry China wingnut extracted by SPME.The principal components are trans-caryophyllene (23.3%), α-bisabolene (17.75 % ), α-selinene ( 12.69 % ), nerolidol (8.35 % ) and δ-cadinene (7.0 % ). The quantitative and qualitative differences both have been found among the chemical composition of three phases of China wingnut. This is the first report describing the volatile odor composition of this species.
