In spite of alternative methods to decrease or to end up illnessess, which affect the human race, the multidisciplinary researches of active ingredients in plants establish an important tool in the medical chemistry. Besides, the botanical and phytochemical studies, plant researches have been developed by many research groups to elucidate Brazilian plants’ main composition. However few investigations were carried out about specific active ingredients in such plants. This study was developed using a sylvestral fruit tree native of the Brazilian forest, the Eugenia uniflora L., from Mirtaceas family. The main goal was focused on the extraction methods. In this sense, Clevenger extraction was the best yield in relation to SFE and Soxhlet. The SFE method presented good yield but presented a great amount of components in the final extract. The essential oil extracted was analyzed by HRGC/FID showing a vast range of polarity and boiling point compounds. Beside it analytical solid phase extraction method was used for clean it up and obtain separated class of compound which was fractionated and studied by HRGC/FID and HRGC/MS.

KEY WORDS: Eugenia uniflora; linalol; gas chromatography; SFE
