Abstract

The essential oil obtained by hydrodistillation of dried leaves of Psidium cattleianum var.cattleianum was analysed by gas chromatography (GC) and combined gas chromatography-mass spectrometry (GC-MS). A total of seventy six compounds, representing 97.5% of the oil were identified. The major constituents of the essential oil were caryophyllene oxide (29.56%), alloaromadendrene oxide-(1) (6.82%), 12-oxabicyclo [9.1.0] dodeca-3,7-diene (5.85%) and 1H-cycloprop[e]azulene (3.49%).  High concentration of caryophyllene oxide in the oil suggests its usefulness as natural preservative in food industry.  The terpenic and ester compounds could contribute to the aroma of P.cattleianum var. cattleianum.

 

Key words: Psidium cattleianum var. cattleianum, essential oil, caryophyllene oxide.
