Lin Zheng-kui and Hua Ying-fang

Abstract:
This paper shows the chemical constituents of the essential oils from the leaves of Cinnamoum pauciflorum Nees. By applying the techniques of fractional distillation, column chromatography, TlC, GC and IR, the following 13 components have been separated and identified: three monoterpenes每汐每pinene (1.28%), camphene (0.17%), and p-cymenc (0.14%); five oxygenated monoterpenes每1,8-cineole (0.85%), lina-lool (14.35%), 汐-terpineol (0.22%), safrole (69.70%) and eugenol (4.20%), two aldehyde compoundes每nonyladehyde (0.16%) and decytadehyde (0.40%); two sesquiter每pene每汕每caryophyllene (0.11%) and 汕每bisabolene (0.05%); one oxygenated sesquiter每pene-nerolidol (0.75%). In addition, the variations of the content of the major components of tile oils in various months have been determined.
