- Phytochemical investigation of the non-polar extract of Clusia burle-marxii led to the identification of a new steroid (1), along with friedelinol (2), β-sitosterol (3), friedelin (4), stigmast-5-en-3β,7β-diol (5), stigmast-5-en-3β,7α-diol (6), stigmasterol (7), sitostenone (8), betulinic acid (9), butyrospermol (10), euphol (11), betulin aldehyde (12), 2,2-dimethyl-5-hydroxy-7-phenyl-chromane (13), 6-deoxyisojacareubin (14), padiaxanthone (15) and betulonic acid (16). This is the first report of the identification of compounds 5, 6 and 10 in the family, the first report of compounds 14 and 15 in the genus, and the first report of compounds 2, 3, 7, 8, 12, 16 in the species. Chemotaxonomic significance of these compounds is described herein.
