Abstract

A reversed-phase high-performance liquid-chromatographic method for the determination of caffeine and theophylline in commercial guarana samples (drug obtained from the seeds of Paulinia cupana Kunth, Sapindaceae of the Amazon Region) and in Cola spp. samples is described and discussed. The methodology developed is simple and rapid with a minimum of samples preparation required. A comparison of five different techniques for the extraction of caffeine and theophylline is discussed. Furthermore the quantitative determination of caffeine and theophylline in five samples of Brasilian guarana, in two samples of dietetic products containing guarana, in two samples of Cola extract and in three of Cola seed powder are reported.
