Abstract The chemistry of Melastomataceae is poorly known. According to previous studies, this family is characterized by tannins (Cronquist, 1981, 1988). Lichexanthone, palmitic acid, betulinic acid, ~-sitosterol, (-)-pinoresinol, 4',5,7 -trihydroxy-6,8-dimethylisoflavone and (2£,6S)-6-( lR,5Z,3aS,9R, 10Z, 12aR)-1,2,3,3a,4,7,8,9,12, 12a-decahydro-9hydroxy-3a,6, 1 O-trimethylcyc1opentanocycloundecen-l-yl]-2-methyl-hept-2-enoic acid were reported from the dichloromethane extract of branches of H. fascicularis (Calder6n et aI., 2002). To our knowledge this is the only study reported so far about the chemical composition of Henriettella species
