Pure caffeine is a white, tasteless substance that makes up as much as 5% of. the weight of tea leaves. By structure, caffeine is closely related to the purine bases, guanine and adenine, found in deoxyribonucleic acids (DNA).
The aim of this study was to determine the content of. caffeine in five types of tea (white, yellow, green, oolong, black) and two types of matÃ© tea (green matÃ© and roasted. matÃ© tea). The content of caffeine was determined by using four different methods: extraction with chloroform, micromethod, method with lead-acetate and high performance liquid chromatography method (HPLC-PDA).
