O(2),1,9- trimethyluric acid and 1,3,7,9 - tetramethyluric acid in leaves of different coffeea species
O (2), 1,9 - Trimethyluric acid and 1,3,7,9 - tetramethyluric acid were isolated from young leaves of Coffea liberica, C. arnoldiana, C. dewevrei var. excelsa and var. aruwimiensis. The first purine has not been found before in nature; its identification required the synthesis of nearly all of its possible isomers
