摘要

The chemical composition of the volatile oil extracted from aerial parts (twigs,leaves and flowers) of Michelia foveolata growing wild in Vietnam was investigated by combination of column chromatography,GC (retention indices),GC-MS and 13C-NMR spectroscopy.Fifty-eight components were identified,with sabinene (32.4%) and terpinen-4-ol (13.7%) as the main constituents.The essential oil was tested against 11 bacteria using the agar disc diffusion method,and exhibited a significant antibacterial activity against Salmonella enterica,Staphylococcus epidermidis,Staphylococcus aureus and Bacillus cereus (MICs=2-4 mu l/ml).
