Resumo: | Nitrogenous alkaloids of the methyl xanthine family are derived from purine bases and xanthines, the main ones being caffeine, theobromine and theophylline. Theobromine A dimethylated xanthine, has a less basic character than caffeine and can be solubilized in alcohol, chlorinated organic solvents and water can be found and isolated in cocoa and derivatives or as a result of caffeine metabolism, responsible for the feeling of well-being, pleasure. Being that studies have been since the years of 1536 that the Spaniards used medicinally like treatment of several diseases. It is a very ingested natural alkaloid and has numerous pharmacological effects underway in several studies developed mainly action on the central nervous system. For this work, samples of industrialized chocolate powder were analyzed to verify the presence of this compound and quantified if there is actually pre- established quantity in its packaging used a known standard and the result was compared through spectrophotometry. To quantify the samples, the UV-Vis spectrophotometer was used and for the construction of a calibration curve, it used a theobromine standard in 5 different concentrations. It was developed in triplicates to confirm analyzes and make a comparison of all these data through tables with mean and standard deviation. |

Os alcaloides nitrogenados da família metil xantina são derivados de bases púricas e das xantinas, as principais são a cafeína, teobromina e teofilina. Teobromina uma metil xantina bimetilada tem caráter menos básico que a cafeína podendo ser solubilizada em álcool, solventes orgânicos clorados e água podendo ser encontrada e isolada no cacau e derivados ou como resultado do metabolismo da cafeína, responsável por a sensação de bem-estar e prazer. Sendo que se têm estudos desde os anos de 1536 que os espanhóis utilizavam medicinalmente como tratamento de várias doenças. É um alcaloide natural muito ingerido e apresenta inúmeros efeitos farmacológicos em andamento em vários estudos desenvolvidos principalmente ação no sistema nervoso central. Para esse trabalho foi analisado amostras de chocolate em pó industrializado para verificar a presença desse composto e quantificado se realmente há quantidade pré-estabelecida em sua embalagem usou um padrão conhecido e foi comparado o resultado, através da espectrofotometria. Para quantificar as amostras foi usado o espectrofotômetro UV- Vis e para construção de uma curva de calibração, utilizou um padrão de teobromina em 5 concentrações diferentes. Foi desenvolvido em triplicatas para confirmação de análises, e fazer um comparativo de todos esses dados através de tabelas com média e desvio padrão.
