Chemical constituents of the essential oil from Syzygium cordatum (Myrtaceae)
Essential oil was extracted from dried leaves of Syzygium cordatum by hydrodistillation. The components were identified by gas chromatography (GC/FID) and gas chromatography coupled with mass spectrometry (GC/MS). Sixty compounds representing 79% of the S. cordatum oil were identified. The main constituents were 6,10,14-trimethylpentadecane-2-one (14.4%), 2,3-butanediol diacetate (13.3%), n-hexadeconic acid (7.2%), ethane, 2-chloro-1,-bis(2 chloroethoxy) (6.2%), Isopentyloxyethyl acetate (5.03%), methane and bis (2-chloroethoxy) (3.8%).
