HPLC determination of caffeine and theophylline inPaullinia cupana Kunth (Guarana) and Cola spp. samples

Summary A reversed-phase high-performance liquid-chromatographic method for the determination of caffeine and theophylline in commercial guarana samples (drug obtained from the seeds ofPaulinia cupana Kunth,Sapindaceae of the Amazon Region) and inCola spp. samples is described and discussed. The met...

abstract	Summary A reversed-phase high-performance liquid-chromatographic method for the determination of caffeine and theophylline in commercial guarana samples (drug obtained from the seeds ofPaulinia cupana Kunth,Sapindaceae of the Amazon Region) and inCola spp. samples is described and discussed. The methodology developed is simple and rapid with a minimum of samples preparation required. A comparision 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 ofCola extract and in three ofCola seed powder are reported. © Springer-Verlag 1985
