The study of volatile constituents of the fruit contributes to the indication for different applications such as in food, pharmaceutical and cosmetics. The importance of research volatile compounds in berries is of the fact that these results point to their use, and to arouse the interest of producers for its commercial cultivation. The objective of this work was to the identification of volatile constituents of essential oil of fruits of the pajeuzeiro (Triplaris sp.). The activities were conducted in the Centro de Ciências Agrárias - CCA of the Universidade Federal do Piauí, Teresina, PI city. The fruits were collected in the of Beneditinos, PI city. In the extraction of essential oil it was used the technique of hydrodistillation and the identification of constituents was performed by gas chromatography / mass spectrometry - GC/MS. It was observed 8 (eight) of 12 (twelve) substances extracted with the major constituents: the methyl palmitate (21.67%) and 10-octadecenoate of methyl (21.72%).
