Title: Chemical composition of Thymus vulgaris L. (Thyme) essential oil from the Rio de Janeiro state, Brazil
Abstract: The essential oil from fresh leaves of Thymus vulgaris L. from Rio de Janeiro State, Brazil, was isolated by hydrodistillation and analyzed through a combination of GC and GC/MS. Compounds representing 95.1 % of the oil were identified. Thirty-nine constituents were detected, of which twenty-eight were identified according to their chromatographic retention indices and mass spectra. The major constituents of the oil were thymol (44.7 %), p-cymene (18.6 %) and ?-terpinene (16.5%).
