The apicomplexan parasite Toxoplasma gondii causes toxoplasmosis, a ubiquitous and cosmopolitan parasitosis, generally asymptomatic and potentially dangerous for the fetus and highly immunocompromised patients. Pyrimethamine and sulfadiazine, supplemented with folic acid, are the drugs of choice to treating the disease, but they produce severe side effects and treatments fail due to drug resistance. New anti-Toxoplasma compounds are needed, and natural compounds can be a good source for obtaining them.

Fourteen undescribed compounds including five neoclerodanes (1-5), three labdanes (12-14), three pimarane (15-17) derivatives, one carbamate (24) and two clovamide-type amides (25 and 26), along with twenty-two known compounds (6-11, 18-23 and 27-36) were isolated from the tuber and stem of Icacina mannii. Their structures were elucidated by 1D and 2D NMR and HR-ESI-MS data analysis, and by comparing their NMR data with those of the literature.
