|Title:||Essential Oils Of The Species Of Annonaceae Growing Wild In The State Of Para, Brazil: Guatteria Schomburgkiana Mart. And Pseudoxandra Cuspidata Maas [Óleos Essenciais De Espécies De Annonaceae Que Ocorrem No Pará: Guatteria Schomburgkiana Mart. E Pseudoxandra Cuspidata Maas]|
|Abstract:||The essential oils of Guatteria schomburgkiana and Pseudoxendra cuspidata, two species of Annonaceae, were obtained by hydrodistillation in Clevenger-type apparatus, and analyzed by GC/MS and GC/FID. The major components identified in the oils from G. schomburgkiene were spathulenol (leaf: 22.4%, fine stem: 14.0%, stem: 21.6%) and caryophyllene oxide (leaf: 14.7%, fine stem: 25.2%, stem: 26.7%). The oils from P. cuspidata were rich in pinenes: α- e β-pinene (leaf: 78.4%, fruit: 88.1 %, fine stem: 72.2%, stem: 55.7%). The high percentage of the monoterpenes α- and β-pinene in the essential oils of P. cuspidata are unusual for Annonaceae species; as the same way the high oil yield in the leaves and fruits of this species (leaves: 1.9%, fruits: 1.3%). The oils of G. schomburgkiana are sesquiterpenoids in nature, which occurs in the complex mixture. This is the first report of the chemical composition of the essential oils of P. cuspidata and G. schomburgkiana.|
