Tea is one of the most widely consumed beverages in the world, and is produced from the tea plant Camellia sinensis. Depending on the processing methods of the leaves of Camellia sinensis after harvesting, green, oolong, or black tea is obtained. This Application Note shows the comprehensive 2D-LC analysis of purine alkaloids and catechins in green and black tea using the Agilent 1290 Infi nity II 2D-LC solution. The precision of retention time and peak volume is determined, and the purine alkaloids caffeine and theobromine as well as the catechins catechin, epicatechin, and epigallocatechin gallate contained in green and black tea are quantified.
