It was analyzed, by high performance liquid chromatography - HPLC, low molecular weight phenolic compounds (Gallic Acid, 5-(hydroxymethyl)furfural(HMF), Furfural, Vanillic Acid, Syringc Acid, Vanillin, Syringaldehyde, Coniferaldehyde, Sinapaldehyde and Coumarin) in aged cachaças (sugar cane spirits), originated of all the producing regions of the Ceará State and in extracts of Amburana cearensis (Fr. All.) A. C. Smith. The objective it was stablished the profile of these compounds in the cachaça from Ceará and also investigated the potential of the extracts of Amburana as source of these analytes in cachaça on the aging period. The validation of the analytic methodology, based on procedures used for the analysis of these substances in different aging beverages, it constituted the initial point of this work. Soon after, the comparison of the phenolics content was contemplated in extracts of Amburana in relation to the oak and Balm. In a third moment, they were researched routines for optimize the gain in the extracts of Amburana and, finally, they took place analyses in aged cachaças. The found values were compared with aged commercial cachaças of great acceptance by the consumers. In relation to the analytic method, the reached results demonstrated the conformity of the methodology before all the necessary parameters so that the analytic procedure obtained the status of Validated Method. The variations, and the new stages proposed for the most usual procedures to obtaining of woods extracts, they presented satisfactory results and the profile, so much qualitative as quantitative, obtained for the low molecular weight phenolic compounds for the cachaça from Ceará, it was revealed compatible with the most popular commercial cachaças, leaders in sales in the States of Ceará, Pernambuco and still with the more another one originated of state of Minas Gerais and distributed nationally by a great supermarket net. This way, the work supplies important information for the conduction the aging cachaças, with or without the employment of extracts, and still for the evaluation of the truth, or not, aging attributed to one cachaça.
