Abstract:The aims was to understand the volatile components in leaves of Myrtaceae, six species, including Eugenia uniflora, Syzygium hainanense, S. hancei, Melaleuca bracteata, M. leucadendron, and Eucalyptus citriodora, were studied by SPME/GC/MS. The results showed that major volatile components in leaves of 6 Myrtaceous plants were terpenes, being rich in health protection components. The common volatile components were (Z)-β-ocimene, β-caryophyllene, myrcene, γ-terpinene and alloaromadendrene. It is suggested that the health function of volatile components from these Myrtaceous plants could be developed and utilized.
