Chemical investigation of the lichen Dirinaria applanata led to isolate nine compounds including a new hopane derivative, 1-acetoxy-21-hopane-3,22-diol (1) together with six phenolic compounds naming divaricatinic acid (2), methyl divaricatinate (3), methyl--orcinolcarboxylate (4), methyl haematommate (5), divarinol (6), ramalinic acid A (7), and two xanthones namely lichenxanthone (8), 4,5-dichlorolichenxanthone (9). Their structures were elucidated by spectroscopic data in combination with published literature. Except compound 2, all compounds were isolated from this species for the first time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
