Volatiles from Syzygium paniculatum fruit.

The volatile compounds of Syzygium paniculatum Banks ex Gaertn. fruit were isolated by simultaneous distillation-solvent extraction and analyzed by gas chromatography-flame ionization detectection and gas chromatography-mass spectrometry. A total of 155 volatile constituents were identified, accounting for 24.5 mg/kg of the fruit composition. Major compounds were alpha-pinene (32.8% of the total composition), (Z)-beta-ocimene (21.8%), limonene (6.9%), and alpha-terpineol (5.1%), indicating that the volatile composition of the fruit is more rich in terpenes.
