Essential Oil Composition of Vismia macrophylla Leaves (Guttiferae) [PDF]

Natural Product Communications, 2011
The essential oil from Vismia macrophylla Kunth (Guttiferae) leaves, extracted by hydrodistillation, was analyzed by GC/MS. The oil obtained (yield 0.11%) contained twenty-eight compounds, which were identified from their retention indices and by comparison of their mass spectra with those in the Wiley GC-MS Library data base. The major components were
