Abstract Clusia nemorosa has been widely used in folk medicine to treat various ailments, including headaches and inflammation. Investigation of the fruits of Clusia nemorosa Clusiaceae led to the isolation and characterization of a new phloroglucinol derivative, named 6S,8S,28S-nemorosic acid 1, together with seven known compounds: friedelin 2, β-sitosterol 3, stigmasterol 4, β-sitosterol glycoside 5, kaempferol 6, quercetin 7 and dimethyl citrate 8. The structures were determined by extensive 1D- and 2D-NMR, CD and MS spectroscopic analyses. View Full-Text
