Chemical Constituents of the Volatile Oils from Leaves of Michelia macclurei Dandy

Abstract:

The volatile oils from leaves of Michelia macclurei were extracted by hydrodistillation, and analyzed by gas chromatography-mass spectrometry (GC-MS). Sixty-one peaks were detected. Among them, forty-five compounds were identified, accounting for 91.41% of the total volatile oils. The major compositions were caryophyllene (18.74%), β-elemene (14.56%), elemol (13.14%), γ-elemene (9.18%), α-eudesmol (7.22%), α-caryophyllene (5.20%) and γ-eudesmol (4.90%), etc.
