Chemical structures of some of the compounds relevant to this study.
(A) Structure of the major alkaloids of U. tomentosa. The individual compounds differ in configuration at C-3, C-7, C-15, C-19 and C-20. (B) Structure of quinovic acid (R = H) and its glycosides (R = several sugars), as well as (C) of 7-deoxyloganic acid, all of them isolated from U. tomentosa.
