[Objective] The research aimed to study the distribution of volatile components in different parts of Michelia yunnanensis flowers. [Method] The volatile components in different parts of M. yunnanensis flowers were extracted by headspace solid-phase micro-extraction(HS-SPME). And the composition was analyzed by gas chromatography-mass spectrometry(GC-MS). [Result] Twenty-eight compounds were identified from receptacle extracts. Among them, β-elemene(21.07%), caryophyllene(30.78%) and germacrene-D(15.41%) were main components. Twenty-seven compounds were identified from petal extracts. And the major components were butyl acetate(62.56%), ethyl acetate(6.36%), 2, 4-toluene diisocyanate(4.67%), 2, 4-dimethyl-5-formyl-3-nitrile pyrrole(4.04%) and 2-methyl-ethyl propionate(4.13%). Nineteen compounds were identified from filaments extracts. And the major components were 2-methyl-1-propanol(28.34%), butyl acetate(20.93%), 2, 4-toluene diisocyanate(18.58%) and 2, 4-dimethyl-5-formyl-3-nitrile pyrrole(16.29%). [Conclusion] The medicinal ingredients were mainly distributed in the receptacle of M. yunnanensis flowers and the aroma components were mainly distributed in the petals and filaments.
