Hannoa
Hannoa
Hannoa is a plant traditionally used for its unknown medicinal properties in unstudied cultures. Scientific evidence suggests that quassinoids from Hannoa chlorantha exhibit high antiplasmodial activity against *P. falciparum*, with 15-desacetylundulatone being the most active compound in vivo, though further research is needed to confirm these findings. The quassinoids isolated from Hannoa klaineana showed limited or no activity against tumor cells and were generally less potent than conventional antibiotics and antifungal agents like gentamicin and ketoconazole. Notably, chimpanzees in Mount Assirik prefer closed-canopy habitats for nesting and use specific tree species; however, this information is unrelated to the medicinal properties of Hannoa. Safety concerns are currently unreported, with no major issues recorded. There are also no known drug interactions associated with Hannoa.

What the science says
- Four quassinoids from Hannoa chlorantha showed varying antiplasmodial activities, with 15-desacetylundulatone being the most active.
- Of five quassinoids isolated from Hannoa klaineana, only one showed activity against tumor cells, while others were more toxic or inactive.
- Both Hannoa plant extract formulations showed some antimicrobial activity against selected bacteria and fungi, but their effects were generally less potent than those of gentamicin and ketoconazole.
- The study found that chimpanzees in Mount Assirik prefer nesting in closed-canopy habitats, using trees like gallery forests, with a nest decay rate of about 69 days.
