Volatile constituents were isolated from genipap (Genipa americana L.) fruit by simultaneous steam distillation-solvent extraction according to Likens-Nickerson. Compounds were identified by capillary GC-MS. Ninetyeight compounds were identified in the aroma concentrate, of which hexadecanoic acid, octadecanoic acid, tetradecanoic acid, linalool and limonene were found to be the major constituents. Carboxylic acids, with their acidic and harsh notes, should play an important role in the flavor of the fruit.
