Opis:Myrcianthes is a Myrtaceous genus of flowering plants of about 30 to 40 species, distributed in the American continent. The aim of this work was to study the chemical composition of the foliar essential oil from M. fragrans growing wild in central Costa Rica. The essential oil was obtained through the steam distillation process in a Clevenger type apparatus. The chemical composition of the oil was performed by capillary gas chromatography with a flame detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS) using the retention indices on a DB-5 type capillary column in addition to mass spectral fragmentation patterns. A total of 98 compounds were identified, accounting for 98.8% of the total amount of the oil. The major constituents in the leaf oil were (E)-methyl cinnamate (39.6%), limonene (34.6%), α-pinene (6.8%), and linalool (6.8%). This is the first report of (E)-methyl cinnamate occurring in oils of this plant genus. These findings appear to suggest a new chemotype of M. fragrans.
