title: [Studies on chemical constituents in essential oil from wild Atractylodes lancea in dabie mountains].
abstract: The chemical constituents in essential oil of wild Atractylodes lancea (Thumb.) DC. from Dabie Mountains were studied. The essential oil was extracted by simultaneous distillation and extraction equipment and analyzed by gas chromatography-mass spectrometry method. 49 compounds were identified and they represent 92.49% of the total peak aeras. The extraction method and solvent selection of the essential oil were studied. The oil yields and major constituents from Atractylodes lancea (Thumb.) DC. from Dabie Mountains were contrasted to that had been reported. The results showed that Atractylodes lancea (Thumb.) DC. from Dabie Mountains had more essential oil (10.14%) and there were more constituents in it. The main constituents in the essential oil were hinesol, beta-eudesmol, 1H-cyclopropa (a) naphthalene, 1a,2,3,5,6,7,7a,7b-octaphdro-1,1,7,7a-tetramethyl-, [1aR-(1a. alpha, 7. alpha, 7a. alpha,7b. alpha-)] -and gamma-eudesmol. Both the major constituents and contents were different from that had been reported.
